Given numbers are 981, 678, 415, 458

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 678 are 2 x 3 x 113

Prime factors of 415 are 5 x 83

Prime factors of 458 are 2 x 229

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

Given numbers are 981, 678, 415, 458

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

Apply this formula for all numbers.

Step1:

LCM(981, 678) = 221706

GCD(981, 678) = ( 981 x 678 ) / 221706

= 981 / 678

= 981

Step2:

LCM(3, 415) = 1245

GCD(3, 415) = ( 3 x 415 ) / 1245

= 3 / 415

= 3

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 981, 678, 415, 458 is 1
