Given numbers are 140, 695, 815, 172

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 695 are 5 x 139

Prime factors of 815 are 5 x 163

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 140, 695, 815, 172

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

Apply this formula for all numbers.

Step1:

LCM(140, 695) = 19460

GCD(140, 695) = ( 140 x 695 ) / 19460

= 140 / 695

= 140

Step2:

LCM(5, 815) = 815

GCD(5, 815) = ( 5 x 815 ) / 815

= 5 / 815

= 5

Step3:

LCM(5, 172) = 860

GCD(5, 172) = ( 5 x 172 ) / 860

= 5 / 172

= 5

So, Greatest Common Divisor of 140, 695, 815, 172 is 1
