Given numbers are 170, 624, 724, 991

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 724 are 2 x 2 x 181

Prime factors of 991 are 991

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

Given numbers are 170, 624, 724, 991

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

Apply this formula for all numbers.

Step1:

LCM(170, 624) = 53040

GCD(170, 624) = ( 170 x 624 ) / 53040

= 170 / 624

= 170

Step2:

LCM(2, 724) = 724

GCD(2, 724) = ( 2 x 724 ) / 724

= 2 / 724

= 2

Step3:

LCM(2, 991) = 1982

GCD(2, 991) = ( 2 x 991 ) / 1982

= 2 / 991

= 2

So, Greatest Common Divisor of 170, 624, 724, 991 is 1
