Given numbers are 705, 372, 171, 620

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 372 are 2 x 2 x 3 x 31

Prime factors of 171 are 3 x 3 x 19

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 705, 372, 171, 620

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

Apply this formula for all numbers.

Step1:

LCM(705, 372) = 87420

GCD(705, 372) = ( 705 x 372 ) / 87420

= 705 / 372

= 705

Step2:

LCM(3, 171) = 171

GCD(3, 171) = ( 3 x 171 ) / 171

= 3 / 171

= 3

Step3:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

So, Greatest Common Divisor of 705, 372, 171, 620 is 1
