Given numbers are 278, 680, 118, 905

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 118 are 2 x 59

Prime factors of 905 are 5 x 181

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

Given numbers are 278, 680, 118, 905

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

Apply this formula for all numbers.

Step1:

LCM(278, 680) = 94520

GCD(278, 680) = ( 278 x 680 ) / 94520

= 278 / 680

= 278

Step2:

LCM(2, 118) = 118

GCD(2, 118) = ( 2 x 118 ) / 118

= 2 / 118

= 2

Step3:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

So, Greatest Common Divisor of 278, 680, 118, 905 is 1
