GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(751, 421) = 316171
GCD(751, 421) = ( 751 x 421 ) / 316171
= 751 / 421
= 751
Step2:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 751, 421, 931, 691 is 1
