Steps to Calculate GCD of 147, 379, 407, 643 using LCM Formula
Given numbers are 147, 379, 407, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 379) = 55713
GCD(147, 379) = ( 147 x 379 ) / 55713
= 147 / 379
= 147
Step2:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 147, 379, 407, 643 is 1
