The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 716 are 2 x 2 x 179

Prime factors of 777 are 3 x 7 x 37

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 423, 716, 777, 660

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

Apply this formula for all numbers.

Step1:

LCM(423, 716) = 302868

GCD(423, 716) = ( 423 x 716 ) / 302868

= 423 / 716

= 423

Step2:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 423, 716, 777, 660 is 1
