GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 639) = 465192
GCD(728, 639) = ( 728 x 639 ) / 465192
= 728 / 639
= 728
Step2:
LCM(1, 974) = 974
GCD(1, 974) = ( 1 x 974 ) / 974
= 1 / 974
= 1
Step3:
LCM(1, 468) = 468
GCD(1, 468) = ( 1 x 468 ) / 468
= 1 / 468
= 1
So, Greatest Common Divisor of 728, 639, 974, 468 is 1
