Given numbers are 987, 165, 986, 670

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 165 are 3 x 5 x 11

Prime factors of 986 are 2 x 17 x 29

Prime factors of 670 are 2 x 5 x 67

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

Given numbers are 987, 165, 986, 670

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

Apply this formula for all numbers.

Step1:

LCM(987, 165) = 54285

GCD(987, 165) = ( 987 x 165 ) / 54285

= 987 / 165

= 987

Step2:

LCM(3, 986) = 2958

GCD(3, 986) = ( 3 x 986 ) / 2958

= 3 / 986

= 3

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 987, 165, 986, 670 is 1
