Given numbers are 278, 915, 956, 240

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 915 are 3 x 5 x 61

Prime factors of 956 are 2 x 2 x 239

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

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

Given numbers are 278, 915, 956, 240

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

Apply this formula for all numbers.

Step1:

LCM(278, 915) = 254370

GCD(278, 915) = ( 278 x 915 ) / 254370

= 278 / 915

= 278

Step2:

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

= 1 / 956

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 278, 915, 956, 240 is 1
