Given numbers are 278, 707, 570, 861

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 707 are 7 x 101

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 278, 707, 570, 861

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

Apply this formula for all numbers.

Step1:

LCM(278, 707) = 196546

GCD(278, 707) = ( 278 x 707 ) / 196546

= 278 / 707

= 278

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 278, 707, 570, 861 is 1
