R. S. Aggarwal Solutions for Chapter: H.C.F. and L.C.M., Exercise 1: EXERCISE 2A

The product of two numbers is $1280$ and their H.C.F. is $8$. The L.C.M. of these numbers is:

The product of two numbers is $4107$ and their H.C.F. is $37$. The larger number is:

The number nearest to $43582$ divisible by each of $25, 50, 75$ is:

The H.C.F. of two numbers is $15$ and their product is $6300$. How many such pairs of numbers are there?

The H.C.F. of two numbers is $13$ and their L.C.M. is $273$. If each number is larger than $13$, then the sum of the numbers is:

The sum of two numbers is $45$ and their difference is $\frac{1}{9}$ of their sum. The L.C.M. of these numbers is:

If two numbers are in the ratio $5:7$ and their L.C.M. is $315$, then their product is:

The number nearest to $10000$, which is exactly divisible by each of the numbers $3, 4, 5, 6, 7, 8$ is:
