Given numbers are 947, 638, 470

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

Apply this formula for all numbers.

Step1:

LCM(947, 638) = 604186

GCD(947, 638) = ( 947 x 638 ) / 604186

= 947 / 638

= 947

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

So, Greatest Common Divisor of 947, 638, 470 is 1
