Steps to Calculate GCD of 22, 79, 42, 40 using LCM Formula
Given numbers are 22, 79, 42, 40
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(22, 79) = 1738
GCD(22, 79) = ( 22 x 79 ) / 1738
= 22 / 79
= 22
Step2:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
Step3:
LCM(1, 40) = 40
GCD(1, 40) = ( 1 x 40 ) / 40
= 1 / 40
= 1
So, Greatest Common Divisor of 22, 79, 42, 40 is 1
