Given numbers are 280, 561, 74, 890

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 561 are 3 x 11 x 17

Prime factors of 74 are 2 x 37

Prime factors of 890 are 2 x 5 x 89

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

Given numbers are 280, 561, 74, 890

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

Apply this formula for all numbers.

Step1:

LCM(280, 561) = 157080

GCD(280, 561) = ( 280 x 561 ) / 157080

= 280 / 561

= 280

Step2:

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

= 1 / 74

= 1

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 280, 561, 74, 890 is 1
