The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 814, 320, 661, 617

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

Apply this formula for all numbers.

Step1:

LCM(814, 320) = 130240

GCD(814, 320) = ( 814 x 320 ) / 130240

= 814 / 320

= 814

Step2:

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

= 2 / 661

= 2

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 814, 320, 661, 617 is 1
