Given numbers are 638, 500, 277, 320
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 500) = 159500
GCD(638, 500) = ( 638 x 500 ) / 159500
= 638 / 500
= 638
Step2:
LCM(2, 277) = 554
GCD(2, 277) = ( 2 x 277 ) / 554
= 2 / 277
= 2
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 638, 500, 277, 320 is 1
