Given numbers are 638, 449, 701, 960
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 449) = 286462
GCD(638, 449) = ( 638 x 449 ) / 286462
= 638 / 449
= 638
Step2:
LCM(1, 701) = 701
GCD(1, 701) = ( 1 x 701 ) / 701
= 1 / 701
= 1
Step3:
LCM(1, 960) = 960
GCD(1, 960) = ( 1 x 960 ) / 960
= 1 / 960
= 1
So, Greatest Common Divisor of 638, 449, 701, 960 is 1
