Steps to Calculate GCD of 395, 393, 971, 641 using LCM Formula
Given numbers are 395, 393, 971, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 393) = 155235
GCD(395, 393) = ( 395 x 393 ) / 155235
= 395 / 393
= 395
Step2:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 395, 393, 971, 641 is 1
