Given numbers are 480, 421, 641, 551

The list of prime factors of all numbers are

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 421 are 421

Prime factors of 641 are 641

Prime factors of 551 are 19 x 29

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

Given numbers are 480, 421, 641, 551

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

Apply this formula for all numbers.

Step1:

LCM(480, 421) = 202080

GCD(480, 421) = ( 480 x 421 ) / 202080

= 480 / 421

= 480

Step2:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

Step3:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

So, Greatest Common Divisor of 480, 421, 641, 551 is 1
