Steps to Calculate GCD of 646, 149, 502, 642 using LCM Formula
Given numbers are 646, 149, 502, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 149) = 96254
GCD(646, 149) = ( 646 x 149 ) / 96254
= 646 / 149
= 646
Step2:
LCM(1, 502) = 502
GCD(1, 502) = ( 1 x 502 ) / 502
= 1 / 502
= 1
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 646, 149, 502, 642 is 1
