Given numbers are 721, 408, 210, 486

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 721, 408, 210, 486

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

Apply this formula for all numbers.

Step1:

LCM(721, 408) = 294168

GCD(721, 408) = ( 721 x 408 ) / 294168

= 721 / 408

= 721

Step2:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 721, 408, 210, 486 is 1
