Given numbers are 280, 747, 861, 876

The list of prime factors of all numbers are

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

Prime factors of 747 are 3 x 3 x 83

Prime factors of 861 are 3 x 7 x 41

Prime factors of 876 are 2 x 2 x 3 x 73

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

Given numbers are 280, 747, 861, 876

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

Apply this formula for all numbers.

Step1:

LCM(280, 747) = 209160

GCD(280, 747) = ( 280 x 747 ) / 209160

= 280 / 747

= 280

Step2:

LCM(1, 861) = 861

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

= 1 / 861

= 1

Step3:

LCM(1, 876) = 876

GCD(1, 876) = ( 1 x 876 ) / 876

= 1 / 876

= 1

So, Greatest Common Divisor of 280, 747, 861, 876 is 1
