Given numbers are 472, 988, 647, 813

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

Apply this formula for all numbers.

Step1:

LCM(472, 988) = 116584

GCD(472, 988) = ( 472 x 988 ) / 116584

= 472 / 988

= 472

Step2:

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

= 4 / 647

= 4

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 472, 988, 647, 813 is 1
