Given numbers are 945, 558, 663, 386

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 663 are 3 x 13 x 17

Prime factors of 386 are 2 x 193

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

Given numbers are 945, 558, 663, 386

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

Apply this formula for all numbers.

Step1:

LCM(945, 558) = 58590

GCD(945, 558) = ( 945 x 558 ) / 58590

= 945 / 558

= 945

Step2:

LCM(9, 663) = 1989

GCD(9, 663) = ( 9 x 663 ) / 1989

= 9 / 663

= 9

Step3:

LCM(3, 386) = 1158

GCD(3, 386) = ( 3 x 386 ) / 1158

= 3 / 386

= 3

So, Greatest Common Divisor of 945, 558, 663, 386 is 1
