Question

if hcf and lcm of two numbers 15and 1440 respectively one of thenumbers is 75 find the other number

Answer 1

HCF*LCM=1st no. *2nd no.
15*1440=75*2nd no.
15*1440/2=2nd no.
21600/2=2nd no.
10800=2nd no.

Therefore, 2nd no. is 10800

Answer 2

HCF*LCM=1st no. *2nd no. 15*1440=75*2nd no. 15*1440/2=2nd no. 21600/2=2nd no. 10800=2nd no.

Therefore, 2nd no. is 10800. We have to find pairs of numbers and that it is fulfill the given criteria.

It has been given by one number and includes 9 factors of second number.

The HCF and LCM are 2 and 20 respectively.
