Steps to Calculate GCD of 99, 68, 64, 61 using LCM Formula
Given numbers are 99, 68, 64, 61
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(99, 68) = 6732
GCD(99, 68) = ( 99 x 68 ) / 6732
= 99 / 68
= 99
Step2:
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
= 1 / 64
= 1
Step3:
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
= 1 / 61
= 1
So, Greatest Common Divisor of 99, 68, 64, 61 is 1
