Steps to Calculate GCD of 557, 411, 647, 478 using LCM Formula
Given numbers are 557, 411, 647, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 411) = 228927
GCD(557, 411) = ( 557 x 411 ) / 228927
= 557 / 411
= 557
Step2:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 557, 411, 647, 478 is 1
