R. Gupta Solutions for Chapter: L.C.M. and H.C.F., Exercise 1: EXERCISE

The product of two numbers is $2160$ and their H.C.F. is $12$. How many such pairs of numbers can be possibly formed?

The sum of two numbers is $216$and their H.C.F. is $27$. These numbers are:

The H.C.F. and the L.C.M. of two numbers are $50$ and $250$ respectively. On dividing one of these numbers by $2, 50$ is obtained as quotient. The numbers are:

The H.C.F. of three numbers is $12$. If the three numbers are in the ratio of $1:2:3$, then the numbers are:

The greatest four-digit number completely divisible by $2, 3, 4$ and $5$ is:

Three bells ring respectively at an interval of $15$seconds, $20$seconds and $24$seconds. If they ring continuously for $12$minutes then how many times, during this period, will they ring together?

The smallest number, on being successively divided by $5, 6, 8, 9$ and $12$ leaves $1$ as remainder in each case and is completely divisible by $13$, will be:

If in the process of finding H.C.F. of two numbers by continued division method, $49$is the last divisor and quotients obtained (from the beginning) are $17, 3$ and $2$ respectively, then the numbers are:
