GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 188) = 36848
GCD(784, 188) = ( 784 x 188 ) / 36848
= 784 / 188
= 784
Step2:
LCM(4, 673) = 2692
GCD(4, 673) = ( 4 x 673 ) / 2692
= 4 / 673
= 4
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 784, 188, 673, 638 is 1
