Given numbers are 720, 172, 521, 344

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 172 are 2 x 2 x 43

Prime factors of 521 are 521

Prime factors of 344 are 2 x 2 x 2 x 43

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

Given numbers are 720, 172, 521, 344

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

Apply this formula for all numbers.

Step1:

LCM(720, 172) = 30960

GCD(720, 172) = ( 720 x 172 ) / 30960

= 720 / 172

= 720

Step2:

LCM(4, 521) = 2084

GCD(4, 521) = ( 4 x 521 ) / 2084

= 4 / 521

= 4

Step3:

LCM(1, 344) = 344

GCD(1, 344) = ( 1 x 344 ) / 344

= 1 / 344

= 1

So, Greatest Common Divisor of 720, 172, 521, 344 is 1
