GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 837) = 59427
GCD(639, 837) = ( 639 x 837 ) / 59427
= 639 / 837
= 639
Step2:
LCM(9, 530) = 4770
GCD(9, 530) = ( 9 x 530 ) / 4770
= 9 / 530
= 9
Step3:
LCM(1, 744) = 744
GCD(1, 744) = ( 1 x 744 ) / 744
= 1 / 744
= 1
So, Greatest Common Divisor of 639, 837, 530, 744 is 1
