Given numbers are 638, 160, 478, 883
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 160) = 51040
GCD(638, 160) = ( 638 x 160 ) / 51040
= 638 / 160
= 638
Step2:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
Step3:
LCM(2, 883) = 1766
GCD(2, 883) = ( 2 x 883 ) / 1766
= 2 / 883
= 2
So, Greatest Common Divisor of 638, 160, 478, 883 is 1
