Steps to Calculate GCD of 74, 72, 86, 40 using LCM Formula
Given numbers are 74, 72, 86, 40
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(74, 72) = 2664
GCD(74, 72) = ( 74 x 72 ) / 2664
= 74 / 72
= 74
Step2:
LCM(2, 86) = 86
GCD(2, 86) = ( 2 x 86 ) / 86
= 2 / 86
= 2
Step3:
LCM(2, 40) = 40
GCD(2, 40) = ( 2 x 40 ) / 40
= 2 / 40
= 2
So, Greatest Common Divisor of 74, 72, 86, 40 is 2
