Question

Find the co prime numbers between $20$ and $50$ .

Accepted Answer

A pair of two natural numbers having no common factor other than $1$ are called co primes.

Co prime numbers between $20$ and $50$ are:

$(21, 22), (21, 23), (21, 25), (21, 26), (21, 29), (21, 31), (21, 32), (21, 34), (21, 37), (21, 38), (21, 40), (21, 41), (21, 43), (21, 44), (21, 46), (21, 47), (22, 23), (22, 25), (22, 27), (22, 29), (22, 31), (22, 35), (22, 37), (22, 39), (22, 41), (22, 43), (22, 45), (22, 47), (22, 49), (23, 24), (23, 25), (23, 26), (23, 27), (23, 28), (23, 29), (23, 30), (23, 31), (23, 32), (23, 33), (23, 34), (23, 35), (23, 36), (23, 37), (23, 38), (23, 39), (23, 40), (23, 41), (23, 42), (23, 43), (23, 44), (23, 45), (23, 47), (23, 48), (23, 49), (24, 25), (24, 29), (24, 31), (24, 35), (24, 37), (24, 41), (24, 43), (24, 47), (24, 49), (25, 26), (25, 27), (25, 28), (25, 29), (25, 31), (25, 32), (25, 33), (25, 34), (25, 36), (25, 37), (25, 38), (25, 39), (25, 41), (25, 42), (25, 43), (25, 44), (25, 46), (25, 47), (25, 48), (25, 49), (26, 27), (26, 29), (26, 31), (26, 33), (26, 35), (26, 37), (26, 41), (26, 43), (26, 45), (26, 47), (26, 49), (27, 28), (27, 29), (27, 31), (27, 32), (27, 34), (27, 35), (27, 37), (27, 38), (27, 40), (27, 41), (27, 43), (27, 44), (27, 46), (27, 47), (27, 49), (28, 29), (28, 31), (28, 33), (28, 37), (28, 39), (28, 41), (28, 43), (28, 45), (28, 47), (29, 30), (29, 31), (29, 32), (29, 33), (29, 34), (29, 35), (29, 36), (29, 37), (29, 38), (29, 39), (29, 40), (29, 41), (29, 42), (29, 43), (29, 44), (29, 45), (29, 46), (29, 47), (29, 48), (29, 49), (30, 31), (30, 37), (30, 41), (30, 43), (30, 47), (30, 49), (31, 32), (31, 33), (31, 34), (31, 35), (31, 36), (31, 37), (31, 38), (31, 39), (31, 40), (31, 41), (31, 42), (31, 43), (31, 44), (31, 45), (31, 46), (31, 47), (31, 48), (31, 49), (32, 33), (32, 35), (32, 37), (32, 39), (32, 41), (32, 43), (32, 45), (32, 47), (32, 49), (33, 34), (33, 35), (33, 37), (33, 38), (33, 40), (33, 41), (33, 43), (33, 46), (33, 47), (33, 49), (34, 35), (34, 37), (34, 39), (34, 41), (34, 43), (34, 45), (34, 47), (34, 49), (35, 36), (35, 37), (35, 38), (35, 39), (35, 41), (35, 43), (35, 44), (35, 46), (35, 47), (35, 48), (36, 37), (36, 41), (36, 43), (36, 47), (36, 49), (37, 38), (37, 39), (37, 40), (37, 41), (37, 42), (37, 43), (37, 44), (37, 45), (37, 46), (37, 47), (37, 48), (37, 49), (38, 39), (38, 41), (38, 43), (38, 45), (38, 47), (38, 49), (39, 40), (39, 41), (39, 43), (39, 44), (39, 46), (39, 47), (39, 49), (40, 41), (40, 43), (40, 47), (40, 49), (41, 42), (41, 43), (41, 44), (41, 45), (41, 46), (41, 47), (41, 48), (41, 49), (42, 43), (42, 47), (43, 44), (43, 45), (43, 46), (43, 47), (43, 48), (43, 49), (44, 45), (44, 47), (44, 49), (45, 46), (45, 47), (45, 49), (46, 47), (46, 49), (47, 48), (47, 49), (48, 49)$
