Steps to Calculate GCD of 721, 123, 655, 587 using LCM Formula
Given numbers are 721, 123, 655, 587
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 123) = 88683
GCD(721, 123) = ( 721 x 123 ) / 88683
= 721 / 123
= 721
Step2:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
Step3:
LCM(1, 587) = 587
GCD(1, 587) = ( 1 x 587 ) / 587
= 1 / 587
= 1
So, Greatest Common Divisor of 721, 123, 655, 587 is 1
