GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(966, 657) = 211554
GCD(966, 657) = ( 966 x 657 ) / 211554
= 966 / 657
= 966
Step2:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 966, 657, 809, 139 is 1
