Given numbers are 521, 681, 784

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

Apply this formula for all numbers.

Step1:

LCM(521, 681) = 354801

GCD(521, 681) = ( 521 x 681 ) / 354801

= 521 / 681

= 521

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 521, 681, 784 is 1
