Given numbers are 521, 865, 784, 417

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

Apply this formula for all numbers.

Step1:

LCM(521, 865) = 450665

GCD(521, 865) = ( 521 x 865 ) / 450665

= 521 / 865

= 521

Step2:

LCM(1, 784) = 784

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

= 1 / 784

= 1

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 521, 865, 784, 417 is 1
