Given numbers are 784, 217, 498, 857

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

Apply this formula for all numbers.

Step1:

LCM(784, 217) = 24304

GCD(784, 217) = ( 784 x 217 ) / 24304

= 784 / 217

= 784

Step2:

LCM(7, 498) = 3486

GCD(7, 498) = ( 7 x 498 ) / 3486

= 7 / 498

= 7

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 784, 217, 498, 857 is 1
