Given numbers are 252, 646, 108, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 646) = 81396
GCD(252, 646) = ( 252 x 646 ) / 81396
= 252 / 646
= 252
Step2:
LCM(2, 108) = 108
GCD(2, 108) = ( 2 x 108 ) / 108
= 2 / 108
= 2
Step3:
LCM(2, 665) = 1330
GCD(2, 665) = ( 2 x 665 ) / 1330
= 2 / 665
= 2
So, Greatest Common Divisor of 252, 646, 108, 665 is 1
