Given numbers are 280, 775, 305, 212

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 775 are 5 x 5 x 31

Prime factors of 305 are 5 x 61

Prime factors of 212 are 2 x 2 x 53

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

Given numbers are 280, 775, 305, 212

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

Apply this formula for all numbers.

Step1:

LCM(280, 775) = 43400

GCD(280, 775) = ( 280 x 775 ) / 43400

= 280 / 775

= 280

Step2:

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

= 5 / 305

= 5

Step3:

LCM(5, 212) = 1060

GCD(5, 212) = ( 5 x 212 ) / 1060

= 5 / 212

= 5

So, Greatest Common Divisor of 280, 775, 305, 212 is 1
