Given numbers are 989, 975, 168, 356

The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

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

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 989, 975, 168, 356

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

Apply this formula for all numbers.

Step1:

LCM(989, 975) = 964275

GCD(989, 975) = ( 989 x 975 ) / 964275

= 989 / 975

= 989

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 989, 975, 168, 356 is 1
