Given numbers are 670, 426, 818, 203

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 426 are 2 x 3 x 71

Prime factors of 818 are 2 x 409

Prime factors of 203 are 7 x 29

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

Given numbers are 670, 426, 818, 203

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

Apply this formula for all numbers.

Step1:

LCM(670, 426) = 142710

GCD(670, 426) = ( 670 x 426 ) / 142710

= 670 / 426

= 670

Step2:

LCM(2, 818) = 818

GCD(2, 818) = ( 2 x 818 ) / 818

= 2 / 818

= 2

Step3:

LCM(2, 203) = 406

GCD(2, 203) = ( 2 x 203 ) / 406

= 2 / 203

= 2

So, Greatest Common Divisor of 670, 426, 818, 203 is 1
