Steps to Calculate GCD of 477, 172, 663, 681 using LCM Formula
Given numbers are 477, 172, 663, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(477, 172) = 82044
GCD(477, 172) = ( 477 x 172 ) / 82044
= 477 / 172
= 477
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 477, 172, 663, 681 is 1
