Given numbers are 655, 440, 424, 986

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 986 are 2 x 17 x 29

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

Given numbers are 655, 440, 424, 986

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

Apply this formula for all numbers.

Step1:

LCM(655, 440) = 57640

GCD(655, 440) = ( 655 x 440 ) / 57640

= 655 / 440

= 655

Step2:

LCM(5, 424) = 2120

GCD(5, 424) = ( 5 x 424 ) / 2120

= 5 / 424

= 5

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 655, 440, 424, 986 is 1
