Given numbers are 784, 188, 673, 638

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
