Given numbers are 420, 242, 501, 263

The list of prime factors of all numbers are

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

Prime factors of 242 are 2 x 11 x 11

Prime factors of 501 are 3 x 167

Prime factors of 263 are 263

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

Given numbers are 420, 242, 501, 263

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

Apply this formula for all numbers.

Step1:

LCM(420, 242) = 50820

GCD(420, 242) = ( 420 x 242 ) / 50820

= 420 / 242

= 420

Step2:

LCM(2, 501) = 1002

GCD(2, 501) = ( 2 x 501 ) / 1002

= 2 / 501

= 2

Step3:

LCM(1, 263) = 263

GCD(1, 263) = ( 1 x 263 ) / 263

= 1 / 263

= 1

So, Greatest Common Divisor of 420, 242, 501, 263 is 1
