Given numbers are 670, 125, 156, 645

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 125 are 5 x 5 x 5

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 670, 125, 156, 645

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

Apply this formula for all numbers.

Step1:

LCM(670, 125) = 16750

GCD(670, 125) = ( 670 x 125 ) / 16750

= 670 / 125

= 670

Step2:

LCM(5, 156) = 780

GCD(5, 156) = ( 5 x 156 ) / 780

= 5 / 156

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 670, 125, 156, 645 is 1
