Steps to Calculate GCD of 124, 653, 309, 663 using LCM Formula
Given numbers are 124, 653, 309, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 653) = 80972
GCD(124, 653) = ( 124 x 653 ) / 80972
= 124 / 653
= 124
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 124, 653, 309, 663 is 1
