Given numbers are 812, 511, 15, 872

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

Apply this formula for all numbers.

Step1:

LCM(812, 511) = 59276

GCD(812, 511) = ( 812 x 511 ) / 59276

= 812 / 511

= 812

Step2:

LCM(7, 15) = 105

GCD(7, 15) = ( 7 x 15 ) / 105

= 7 / 15

= 7

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 812, 511, 15, 872 is 1
