Given numbers are 662, 432, 77, 639
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 432) = 142992
GCD(662, 432) = ( 662 x 432 ) / 142992
= 662 / 432
= 662
Step2:
LCM(2, 77) = 154
GCD(2, 77) = ( 2 x 77 ) / 154
= 2 / 77
= 2
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 662, 432, 77, 639 is 1
