Given numbers are 145, 640, 986, 718

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 986 are 2 x 17 x 29

Prime factors of 718 are 2 x 359

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

Given numbers are 145, 640, 986, 718

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

Apply this formula for all numbers.

Step1:

LCM(145, 640) = 18560

GCD(145, 640) = ( 145 x 640 ) / 18560

= 145 / 640

= 145

Step2:

LCM(5, 986) = 4930

GCD(5, 986) = ( 5 x 986 ) / 4930

= 5 / 986

= 5

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 145, 640, 986, 718 is 1
