Given numbers are 391, 660, 172, 532

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 172 are 2 x 2 x 43

Prime factors of 532 are 2 x 2 x 7 x 19

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

Given numbers are 391, 660, 172, 532

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

Apply this formula for all numbers.

Step1:

LCM(391, 660) = 258060

GCD(391, 660) = ( 391 x 660 ) / 258060

= 391 / 660

= 391

Step2:

LCM(1, 172) = 172

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

= 1 / 172

= 1

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 391, 660, 172, 532 is 1
