Given numbers are 455, 847, 670, 702

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 847 are 7 x 11 x 11

Prime factors of 670 are 2 x 5 x 67

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 455, 847, 670, 702

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

Apply this formula for all numbers.

Step1:

LCM(455, 847) = 55055

GCD(455, 847) = ( 455 x 847 ) / 55055

= 455 / 847

= 455

Step2:

LCM(7, 670) = 4690

GCD(7, 670) = ( 7 x 670 ) / 4690

= 7 / 670

= 7

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 455, 847, 670, 702 is 1
