Given numbers are 278, 280, 148, 511

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 148 are 2 x 2 x 37

Prime factors of 511 are 7 x 73

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

Given numbers are 278, 280, 148, 511

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

Apply this formula for all numbers.

Step1:

LCM(278, 280) = 38920

GCD(278, 280) = ( 278 x 280 ) / 38920

= 278 / 280

= 278

Step2:

LCM(2, 148) = 148

GCD(2, 148) = ( 2 x 148 ) / 148

= 2 / 148

= 2

Step3:

LCM(2, 511) = 1022

GCD(2, 511) = ( 2 x 511 ) / 1022

= 2 / 511

= 2

So, Greatest Common Divisor of 278, 280, 148, 511 is 1
