Given numbers are 497, 262, 487, 420

The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

Prime factors of 262 are 2 x 131

Prime factors of 487 are 487

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 497, 262, 487, 420

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

Apply this formula for all numbers.

Step1:

LCM(497, 262) = 130214

GCD(497, 262) = ( 497 x 262 ) / 130214

= 497 / 262

= 497

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 497, 262, 487, 420 is 1
