GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 931) = 594909
GCD(639, 931) = ( 639 x 931 ) / 594909
= 639 / 931
= 639
Step2:
LCM(1, 895) = 895
GCD(1, 895) = ( 1 x 895 ) / 895
= 1 / 895
= 1
Step3:
LCM(1, 432) = 432
GCD(1, 432) = ( 1 x 432 ) / 432
= 1 / 432
= 1
So, Greatest Common Divisor of 639, 931, 895, 432 is 1
