GCD of numbers is the greatest common divisor

So, the GCD (722, 720, 61, 207) = 1.

Given numbers are 722, 720, 61, 207

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

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

Prime factors of 61 are 61

Prime factors of 207 are 3 x 3 x 23

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

Given numbers are 722, 720, 61, 207

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

Apply this formula for all numbers.

Step1:

LCM(722, 720) = 259920

GCD(722, 720) = ( 722 x 720 ) / 259920

= 722 / 720

= 722

Step2:

LCM(2, 61) = 122

GCD(2, 61) = ( 2 x 61 ) / 122

= 2 / 61

= 2

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 722, 720, 61, 207 is 1
