Given numbers are 280, 212, 173, 172

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 212 are 2 x 2 x 53

Prime factors of 173 are 173

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 280, 212, 173, 172

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

Apply this formula for all numbers.

Step1:

LCM(280, 212) = 14840

GCD(280, 212) = ( 280 x 212 ) / 14840

= 280 / 212

= 280

Step2:

LCM(4, 173) = 692

GCD(4, 173) = ( 4 x 173 ) / 692

= 4 / 173

= 4

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 280, 212, 173, 172 is 1
