Given numbers are 278, 525, 115, 920

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 525 are 3 x 5 x 5 x 7

Prime factors of 115 are 5 x 23

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Given numbers are 278, 525, 115, 920

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

Apply this formula for all numbers.

Step1:

LCM(278, 525) = 145950

GCD(278, 525) = ( 278 x 525 ) / 145950

= 278 / 525

= 278

Step2:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

Step3:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

So, Greatest Common Divisor of 278, 525, 115, 920 is 1
