Given numbers are 215, 666, 680, 386

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 680 are 2 x 2 x 2 x 5 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 215, 666, 680, 386

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

Apply this formula for all numbers.

Step1:

LCM(215, 666) = 143190

GCD(215, 666) = ( 215 x 666 ) / 143190

= 215 / 666

= 215

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 386) = 386

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

= 1 / 386

= 1

So, Greatest Common Divisor of 215, 666, 680, 386 is 1
