Given numbers are 123, 212, 386, 516

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 212 are 2 x 2 x 53

Prime factors of 386 are 2 x 193

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

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

Given numbers are 123, 212, 386, 516

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

Apply this formula for all numbers.

Step1:

LCM(123, 212) = 26076

GCD(123, 212) = ( 123 x 212 ) / 26076

= 123 / 212

= 123

Step2:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

Step3:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

So, Greatest Common Divisor of 123, 212, 386, 516 is 1
