Given numbers are 502, 664, 138, 747
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(502, 664) = 166664
GCD(502, 664) = ( 502 x 664 ) / 166664
= 502 / 664
= 502
Step2:
LCM(2, 138) = 138
GCD(2, 138) = ( 2 x 138 ) / 138
= 2 / 138
= 2
Step3:
LCM(2, 747) = 1494
GCD(2, 747) = ( 2 x 747 ) / 1494
= 2 / 747
= 2
So, Greatest Common Divisor of 502, 664, 138, 747 is 1
