Given numbers are 418, 670, 995, 221

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

Prime factors of 670 are 2 x 5 x 67

Prime factors of 995 are 5 x 199

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 418, 670, 995, 221

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

Apply this formula for all numbers.

Step1:

LCM(418, 670) = 140030

GCD(418, 670) = ( 418 x 670 ) / 140030

= 418 / 670

= 418

Step2:

LCM(2, 995) = 1990

GCD(2, 995) = ( 2 x 995 ) / 1990

= 2 / 995

= 2

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 418, 670, 995, 221 is 1
