GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 429) = 97383
GCD(681, 429) = ( 681 x 429 ) / 97383
= 681 / 429
= 681
Step2:
LCM(3, 728) = 2184
GCD(3, 728) = ( 3 x 728 ) / 2184
= 3 / 728
= 3
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 681, 429, 728, 778 is 1
