The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 754 are 2 x 13 x 29

Prime factors of 451 are 11 x 41

Prime factors of 721 are 7 x 103

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

Given numbers are 278, 754, 451, 721

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

Apply this formula for all numbers.

Step1:

LCM(278, 754) = 104806

GCD(278, 754) = ( 278 x 754 ) / 104806

= 278 / 754

= 278

Step2:

LCM(2, 451) = 902

GCD(2, 451) = ( 2 x 451 ) / 902

= 2 / 451

= 2

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 278, 754, 451, 721 is 1
