Given numbers are 451, 825, 705, 720

The list of prime factors of all numbers are

Prime factors of 451 are 11 x 41

Prime factors of 825 are 3 x 5 x 5 x 11

Prime factors of 705 are 3 x 5 x 47

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

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

Given numbers are 451, 825, 705, 720

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

Apply this formula for all numbers.

Step1:

LCM(451, 825) = 33825

GCD(451, 825) = ( 451 x 825 ) / 33825

= 451 / 825

= 451

Step2:

LCM(11, 705) = 7755

GCD(11, 705) = ( 11 x 705 ) / 7755

= 11 / 705

= 11

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 451, 825, 705, 720 is 1
