Steps to Calculate GCD of 79, 36, 68, 20 using LCM Formula
Given numbers are 79, 36, 68, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(79, 36) = 2844
GCD(79, 36) = ( 79 x 36 ) / 2844
= 79 / 36
= 79
Step2:
LCM(1, 68) = 68
GCD(1, 68) = ( 1 x 68 ) / 68
= 1 / 68
= 1
Step3:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
So, Greatest Common Divisor of 79, 36, 68, 20 is 1
