Given numbers are 617, 218, 803, 687

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

Apply this formula for all numbers.

Step1:

LCM(617, 218) = 134506

GCD(617, 218) = ( 617 x 218 ) / 134506

= 617 / 218

= 617

Step2:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 617, 218, 803, 687 is 1
