Given numbers are 851, 538, 657, 628
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 538) = 457838
GCD(851, 538) = ( 851 x 538 ) / 457838
= 851 / 538
= 851
Step2:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
Step3:
LCM(1, 628) = 628
GCD(1, 628) = ( 1 x 628 ) / 628
= 1 / 628
= 1
So, Greatest Common Divisor of 851, 538, 657, 628 is 1
