Given numbers are 723, 420, 629, 270

The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 629 are 17 x 37

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 723, 420, 629, 270

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

Apply this formula for all numbers.

Step1:

LCM(723, 420) = 101220

GCD(723, 420) = ( 723 x 420 ) / 101220

= 723 / 420

= 723

Step2:

LCM(3, 629) = 1887

GCD(3, 629) = ( 3 x 629 ) / 1887

= 3 / 629

= 3

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 723, 420, 629, 270 is 1
