Given numbers are 987, 806, 975, 458

The list of prime factors of all numbers are

Prime factors of 987 are 3 x 7 x 47

Prime factors of 806 are 2 x 13 x 31

Prime factors of 975 are 3 x 5 x 5 x 13

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 987, 806, 975, 458

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

Apply this formula for all numbers.

Step1:

LCM(987, 806) = 795522

GCD(987, 806) = ( 987 x 806 ) / 795522

= 987 / 806

= 987

Step2:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

Step3:

LCM(1, 458) = 458

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

= 1 / 458

= 1

So, Greatest Common Divisor of 987, 806, 975, 458 is 1
