GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 639) = 499698
GCD(782, 639) = ( 782 x 639 ) / 499698
= 782 / 639
= 782
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
So, Greatest Common Divisor of 782, 639, 156, 570 is 1
