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

Given numbers are 690, 495, 498, 457

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

Apply this formula for all numbers.

Step1:

LCM(690, 495) = 22770

GCD(690, 495) = ( 690 x 495 ) / 22770

= 690 / 495

= 690

Step2:

LCM(15, 498) = 2490

GCD(15, 498) = ( 15 x 498 ) / 2490

= 15 / 498

= 15

Step3:

LCM(3, 457) = 1371

GCD(3, 457) = ( 3 x 457 ) / 1371

= 3 / 457

= 3

So, Greatest Common Divisor of 690, 495, 498, 457 is 1
