The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

Prime factors of 253 are 11 x 23

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 989, 624, 253, 945

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

Apply this formula for all numbers.

Step1:

LCM(989, 624) = 617136

GCD(989, 624) = ( 989 x 624 ) / 617136

= 989 / 624

= 989

Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 989, 624, 253, 945 is 1
