Steps to Calculate GCD of 316, 516, 21, 641 using LCM Formula
Given numbers are 316, 516, 21, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(316, 516) = 40764
GCD(316, 516) = ( 316 x 516 ) / 40764
= 316 / 516
= 316
Step2:
LCM(4, 21) = 84
GCD(4, 21) = ( 4 x 21 ) / 84
= 4 / 21
= 4
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 316, 516, 21, 641 is 1
