GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 638) = 250096
GCD(784, 638) = ( 784 x 638 ) / 250096
= 784 / 638
= 784
Step2:
LCM(2, 976) = 976
GCD(2, 976) = ( 2 x 976 ) / 976
= 2 / 976
= 2
Step3:
LCM(2, 906) = 906
GCD(2, 906) = ( 2 x 906 ) / 906
= 2 / 906
= 2
So, Greatest Common Divisor of 784, 638, 976, 906 is 2
