Given numbers are 631, 913, 520, 819

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

Apply this formula for all numbers.

Step1:

LCM(631, 913) = 576103

GCD(631, 913) = ( 631 x 913 ) / 576103

= 631 / 913

= 631

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 631, 913, 520, 819 is 1
