Steps to Calculate GCD of 79, 57, 65, 12 using LCM Formula
Given numbers are 79, 57, 65, 12
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(79, 57) = 4503
GCD(79, 57) = ( 79 x 57 ) / 4503
= 79 / 57
= 79
Step2:
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
= 1 / 65
= 1
Step3:
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
= 1 / 12
= 1
So, Greatest Common Divisor of 79, 57, 65, 12 is 1
