Given numbers are 648, 822, 255, 454

The list of prime factors of all numbers are

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 822 are 2 x 3 x 137

Prime factors of 255 are 3 x 5 x 17

Prime factors of 454 are 2 x 227

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

Given numbers are 648, 822, 255, 454

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

Apply this formula for all numbers.

Step1:

LCM(648, 822) = 88776

GCD(648, 822) = ( 648 x 822 ) / 88776

= 648 / 822

= 648

Step2:

LCM(6, 255) = 510

GCD(6, 255) = ( 6 x 255 ) / 510

= 6 / 255

= 6

Step3:

LCM(3, 454) = 1362

GCD(3, 454) = ( 3 x 454 ) / 1362

= 3 / 454

= 3

So, Greatest Common Divisor of 648, 822, 255, 454 is 1
