Given numbers are 670, 417, 688, 142

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 417 are 3 x 139

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 142 are 2 x 71

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

Given numbers are 670, 417, 688, 142

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

Apply this formula for all numbers.

Step1:

LCM(670, 417) = 279390

GCD(670, 417) = ( 670 x 417 ) / 279390

= 670 / 417

= 670

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 670, 417, 688, 142 is 1
