GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 422) = 165424
GCD(784, 422) = ( 784 x 422 ) / 165424
= 784 / 422
= 784
Step2:
LCM(2, 996) = 996
GCD(2, 996) = ( 2 x 996 ) / 996
= 2 / 996
= 2
Step3:
LCM(2, 668) = 668
GCD(2, 668) = ( 2 x 668 ) / 668
= 2 / 668
= 2
So, Greatest Common Divisor of 784, 422, 996, 668 is 2
