The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 875 are 5 x 5 x 5 x 7

Prime factors of 670 are 2 x 5 x 67

Prime factors of 221 are 13 x 17

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

Given numbers are 386, 875, 670, 221

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

Apply this formula for all numbers.

Step1:

LCM(386, 875) = 337750

GCD(386, 875) = ( 386 x 875 ) / 337750

= 386 / 875

= 386

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 386, 875, 670, 221 is 1
