Given numbers are 989, 552, 646, 365

The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 646 are 2 x 17 x 19

Prime factors of 365 are 5 x 73

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

Given numbers are 989, 552, 646, 365

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

Apply this formula for all numbers.

Step1:

LCM(989, 552) = 23736

GCD(989, 552) = ( 989 x 552 ) / 23736

= 989 / 552

= 989

Step2:

LCM(23, 646) = 14858

GCD(23, 646) = ( 23 x 646 ) / 14858

= 23 / 646

= 23

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 989, 552, 646, 365 is 1
