GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 442) = 282438
GCD(639, 442) = ( 639 x 442 ) / 282438
= 639 / 442
= 639
Step2:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
Step3:
LCM(1, 316) = 316
GCD(1, 316) = ( 1 x 316 ) / 316
= 1 / 316
= 1
So, Greatest Common Divisor of 639, 442, 779, 316 is 1
