Steps to Calculate GCD of 156, 654, 142, 287 using LCM Formula
Given numbers are 156, 654, 142, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(156, 654) = 17004
GCD(156, 654) = ( 156 x 654 ) / 17004
= 156 / 654
= 156
Step2:
LCM(6, 142) = 426
GCD(6, 142) = ( 6 x 142 ) / 426
= 6 / 142
= 6
Step3:
LCM(2, 287) = 574
GCD(2, 287) = ( 2 x 287 ) / 574
= 2 / 287
= 2
So, Greatest Common Divisor of 156, 654, 142, 287 is 1
