Question

The HCF and LCM of two numbers are 23 and 345 If one number is 115 find the other

Answer 1

Hcf =23
Lcm = 345
1St no. =115
2nd no.=?
Let the second no. be x
Then we know Hcf x lcm = product of two numbers.
23 x 345 = 115x
115x =7935
x=7935÷115
x=69
So, 2nd number = 69

Answer 2

Ans..
Other Number=HCF×LCM÷one number
Other Number= 23×345÷115
Other Number=69
