Given numbers are 720, 725, 770, 630

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 725 are 5 x 5 x 29

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

The highest common occurrence is 5¹

Therefore, GCD of 720, 725, 770, 630 is 5.

Given numbers are 720, 725, 770, 630

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

Apply this formula for all numbers.

Step1:

LCM(720, 725) = 104400

GCD(720, 725) = ( 720 x 725 ) / 104400

= 720 / 725

= 720

Step2:

LCM(5, 770) = 770

GCD(5, 770) = ( 5 x 770 ) / 770

= 5 / 770

= 5

Step3:

LCM(5, 630) = 630

GCD(5, 630) = ( 5 x 630 ) / 630

= 5 / 630

= 5

So, Greatest Common Divisor of 720, 725, 770, 630 is 5
