Given numbers are 307, 280, 672, 172

The list of prime factors of all numbers are

Prime factors of 307 are 307

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

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

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 307, 280, 672, 172

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

Apply this formula for all numbers.

Step1:

LCM(307, 280) = 85960

GCD(307, 280) = ( 307 x 280 ) / 85960

= 307 / 280

= 307

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 172) = 172

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

= 1 / 172

= 1

So, Greatest Common Divisor of 307, 280, 672, 172 is 1
