Given numbers are 628, 240, 728, 281

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 281 are 281

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

Given numbers are 628, 240, 728, 281

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

Apply this formula for all numbers.

Step1:

LCM(628, 240) = 37680

GCD(628, 240) = ( 628 x 240 ) / 37680

= 628 / 240

= 628

Step2:

LCM(4, 728) = 728

GCD(4, 728) = ( 4 x 728 ) / 728

= 4 / 728

= 4

Step3:

LCM(4, 281) = 1124

GCD(4, 281) = ( 4 x 281 ) / 1124

= 4 / 281

= 4

So, Greatest Common Divisor of 628, 240, 728, 281 is 1
