Given numbers are 731, 636, 170, 987

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 170 are 2 x 5 x 17

Prime factors of 987 are 3 x 7 x 47

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

Given numbers are 731, 636, 170, 987

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

Apply this formula for all numbers.

Step1:

LCM(731, 636) = 464916

GCD(731, 636) = ( 731 x 636 ) / 464916

= 731 / 636

= 731

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

So, Greatest Common Divisor of 731, 636, 170, 987 is 1
