Steps to Calculate GCD of 649, 903, 107, 921 using LCM Formula
Given numbers are 649, 903, 107, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 903) = 586047
GCD(649, 903) = ( 649 x 903 ) / 586047
= 649 / 903
= 649
Step2:
LCM(1, 107) = 107
GCD(1, 107) = ( 1 x 107 ) / 107
= 1 / 107
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 649, 903, 107, 921 is 1
