Given numbers are 670, 648, 550, 415

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 415 are 5 x 83

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

Given numbers are 670, 648, 550, 415

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

Apply this formula for all numbers.

Step1:

LCM(670, 648) = 217080

GCD(670, 648) = ( 670 x 648 ) / 217080

= 670 / 648

= 670

Step2:

LCM(2, 550) = 550

GCD(2, 550) = ( 2 x 550 ) / 550

= 2 / 550

= 2

Step3:

LCM(2, 415) = 830

GCD(2, 415) = ( 2 x 415 ) / 830

= 2 / 415

= 2

So, Greatest Common Divisor of 670, 648, 550, 415 is 1
