Given numbers are 784, 376, 15, 947

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(784, 376) = 36848

GCD(784, 376) = ( 784 x 376 ) / 36848

= 784 / 376

= 784

Step2:

LCM(8, 15) = 120

GCD(8, 15) = ( 8 x 15 ) / 120

= 8 / 15

= 8

Step3:

LCM(1, 947) = 947

GCD(1, 947) = ( 1 x 947 ) / 947

= 1 / 947

= 1

So, Greatest Common Divisor of 784, 376, 15, 947 is 1
