GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(964, 998) = 481036
GCD(964, 998) = ( 964 x 998 ) / 481036
= 964 / 998
= 964
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 397) = 794
GCD(2, 397) = ( 2 x 397 ) / 794
= 2 / 397
= 2
So, Greatest Common Divisor of 964, 998, 646, 397 is 1
