Given numbers are 986, 217, 155, 430

The list of prime factors of all numbers are

Prime factors of 986 are 2 x 17 x 29

Prime factors of 217 are 7 x 31

Prime factors of 155 are 5 x 31

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 986, 217, 155, 430

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

Apply this formula for all numbers.

Step1:

LCM(986, 217) = 213962

GCD(986, 217) = ( 986 x 217 ) / 213962

= 986 / 217

= 986

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 430) = 430

GCD(1, 430) = ( 1 x 430 ) / 430

= 1 / 430

= 1

So, Greatest Common Divisor of 986, 217, 155, 430 is 1
