GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 416) = 20384
GCD(637, 416) = ( 637 x 416 ) / 20384
= 637 / 416
= 637
Step2:
LCM(13, 931) = 12103
GCD(13, 931) = ( 13 x 931 ) / 12103
= 13 / 931
= 13
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 637, 416, 931, 861 is 1
