Steps to Calculate GCD of 687, 247, 57, 377 using LCM Formula
Given numbers are 687, 247, 57, 377
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 247) = 169689
GCD(687, 247) = ( 687 x 247 ) / 169689
= 687 / 247
= 687
Step2:
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
= 1 / 57
= 1
Step3:
LCM(1, 377) = 377
GCD(1, 377) = ( 1 x 377 ) / 377
= 1 / 377
= 1
So, Greatest Common Divisor of 687, 247, 57, 377 is 1
