Given numbers are 784, 312, 243, 872

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

Apply this formula for all numbers.

Step1:

LCM(784, 312) = 30576

GCD(784, 312) = ( 784 x 312 ) / 30576

= 784 / 312

= 784

Step2:

LCM(8, 243) = 1944

GCD(8, 243) = ( 8 x 243 ) / 1944

= 8 / 243

= 8

Step3:

LCM(1, 872) = 872

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

= 1 / 872

= 1

So, Greatest Common Divisor of 784, 312, 243, 872 is 1
