Given numbers are 648, 280, 205, 945

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 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 205 are 5 x 41

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 648, 280, 205, 945

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

Apply this formula for all numbers.

Step1:

LCM(648, 280) = 22680

GCD(648, 280) = ( 648 x 280 ) / 22680

= 648 / 280

= 648

Step2:

LCM(8, 205) = 1640

GCD(8, 205) = ( 8 x 205 ) / 1640

= 8 / 205

= 8

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 648, 280, 205, 945 is 1
