Given numbers are 639, 902, 633, 404
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 902) = 576378
GCD(639, 902) = ( 639 x 902 ) / 576378
= 639 / 902
= 639
Step2:
LCM(1, 633) = 633
GCD(1, 633) = ( 1 x 633 ) / 633
= 1 / 633
= 1
Step3:
LCM(1, 404) = 404
GCD(1, 404) = ( 1 x 404 ) / 404
= 1 / 404
= 1
So, Greatest Common Divisor of 639, 902, 633, 404 is 1
