Given numbers are 638, 616, 851, 814
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 616) = 17864
GCD(638, 616) = ( 638 x 616 ) / 17864
= 638 / 616
= 638
Step2:
LCM(22, 851) = 18722
GCD(22, 851) = ( 22 x 851 ) / 18722
= 22 / 851
= 22
Step3:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
So, Greatest Common Divisor of 638, 616, 851, 814 is 1
