Given numbers are 638, 974, 407, 435
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 974) = 310706
GCD(638, 974) = ( 638 x 974 ) / 310706
= 638 / 974
= 638
Step2:
LCM(2, 407) = 814
GCD(2, 407) = ( 2 x 407 ) / 814
= 2 / 407
= 2
Step3:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
So, Greatest Common Divisor of 638, 974, 407, 435 is 1
