Given numbers are 644, 154, 670, 295

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 154 are 2 x 7 x 11

Prime factors of 670 are 2 x 5 x 67

Prime factors of 295 are 5 x 59

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

Given numbers are 644, 154, 670, 295

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

Apply this formula for all numbers.

Step1:

LCM(644, 154) = 7084

GCD(644, 154) = ( 644 x 154 ) / 7084

= 644 / 154

= 644

Step2:

LCM(14, 670) = 4690

GCD(14, 670) = ( 14 x 670 ) / 4690

= 14 / 670

= 14

Step3:

LCM(2, 295) = 590

GCD(2, 295) = ( 2 x 295 ) / 590

= 2 / 295

= 2

So, Greatest Common Divisor of 644, 154, 670, 295 is 1
