Given numbers are 670, 462, 687, 280

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 462 are 2 x 3 x 7 x 11

Prime factors of 687 are 3 x 229

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 670, 462, 687, 280

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

Apply this formula for all numbers.

Step1:

LCM(670, 462) = 154770

GCD(670, 462) = ( 670 x 462 ) / 154770

= 670 / 462

= 670

Step2:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

Step3:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 670, 462, 687, 280 is 1
