Given numbers are 202, 254, 456, 421

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

Prime factors of 254 are 2 x 127

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 421 are 421

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

Given numbers are 202, 254, 456, 421

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

Apply this formula for all numbers.

Step1:

LCM(202, 254) = 25654

GCD(202, 254) = ( 202 x 254 ) / 25654

= 202 / 254

= 202

Step2:

LCM(2, 456) = 456

GCD(2, 456) = ( 2 x 456 ) / 456

= 2 / 456

= 2

Step3:

LCM(2, 421) = 842

GCD(2, 421) = ( 2 x 421 ) / 842

= 2 / 421

= 2

So, Greatest Common Divisor of 202, 254, 456, 421 is 1
