Given numbers are 154, 646, 714, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 646) = 49742
GCD(154, 646) = ( 154 x 646 ) / 49742
= 154 / 646
= 154
Step2:
LCM(2, 714) = 714
GCD(2, 714) = ( 2 x 714 ) / 714
= 2 / 714
= 2
Step3:
LCM(2, 663) = 1326
GCD(2, 663) = ( 2 x 663 ) / 1326
= 2 / 663
= 2
So, Greatest Common Divisor of 154, 646, 714, 663 is 1
