Given numbers are 789, 516, 751, 720

The list of prime factors of all numbers are

Prime factors of 789 are 3 x 263

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 751 are 751

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

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

Given numbers are 789, 516, 751, 720

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

Apply this formula for all numbers.

Step1:

LCM(789, 516) = 135708

GCD(789, 516) = ( 789 x 516 ) / 135708

= 789 / 516

= 789

Step2:

LCM(3, 751) = 2253

GCD(3, 751) = ( 3 x 751 ) / 2253

= 3 / 751

= 3

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 789, 516, 751, 720 is 1
