Given numbers are 276, 720, 420, 709

The list of prime factors of all numbers are

Prime factors of 276 are 2 x 2 x 3 x 23

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

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

Prime factors of 709 are 709

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

Given numbers are 276, 720, 420, 709

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

Apply this formula for all numbers.

Step1:

LCM(276, 720) = 16560

GCD(276, 720) = ( 276 x 720 ) / 16560

= 276 / 720

= 276

Step2:

LCM(12, 420) = 420

GCD(12, 420) = ( 12 x 420 ) / 420

= 12 / 420

= 12

Step3:

LCM(12, 709) = 8508

GCD(12, 709) = ( 12 x 709 ) / 8508

= 12 / 709

= 12

So, Greatest Common Divisor of 276, 720, 420, 709 is 1
