Steps to Calculate GCD of 251, 739, 138, 641 using LCM Formula
Given numbers are 251, 739, 138, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 739) = 185489
GCD(251, 739) = ( 251 x 739 ) / 185489
= 251 / 739
= 251
Step2:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 251, 739, 138, 641 is 1
