Given numbers are 670, 101, 138, 646

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 101 are 101

Prime factors of 138 are 2 x 3 x 23

Prime factors of 646 are 2 x 17 x 19

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

Given numbers are 670, 101, 138, 646

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

Apply this formula for all numbers.

Step1:

LCM(670, 101) = 67670

GCD(670, 101) = ( 670 x 101 ) / 67670

= 670 / 101

= 670

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 670, 101, 138, 646 is 1
