Given numbers are 847, 707, 472, 640

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

Apply this formula for all numbers.

Step1:

LCM(847, 707) = 85547

GCD(847, 707) = ( 847 x 707 ) / 85547

= 847 / 707

= 847

Step2:

LCM(7, 472) = 3304

GCD(7, 472) = ( 7 x 472 ) / 3304

= 7 / 472

= 7

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 847, 707, 472, 640 is 1
