Question

if the HCF and LCM of two numbers are 8 and 280 and one of the numbers is 56 list find the other number

Answer 1

1st no. × 2nd no. = H. C. F. × L. C. M.
56 × 2nd no. = 8× 280
2nd no. = 8× 280/ 56
2nd no. = 40

Answer 2

Answer:

the second number is 40.

Step-by-step explanation:

Firstly, let the second number be x:

Here, we will do this by the formula:

HCF×LCM = product of two numbers

8 × 280     = 56 × x

8 × 280/56= x

40 = x

hence, the second number is 40.

Alternative explanation:

HCF×LCM = product of two numbers

8 × 280     = 56 × 40

2240         = 2240

        hence verified::
