8 and 104 are.
A common prime factor of both 65 and 104 is 13.
They are 26 and 312 respectively
X=13
104
Divide both by their highest common factor, which is 2.
13 is a prime number. It and 8 have no factors in common. Therefore, the least common multiple is 8 x 13 = 104.
104
The Greatest Common Factor of 26 and 104 is 26.
== == === === Factoring each number into product of primes: 78 = 2 x 3 x 13 104 = 2 x 2 x 2 x 13 While the number 2 is a factor for both numbers, it occurrs three times for 104; Therefore, inlude 2 x 2 x 2 in answer The number 3, which is only common to 78, should be included in answer The number 13, which occurs once for each number should be included in answer Therefore, LCM(78,104) = 2 x 2 x 2 x 3 x 13 = 312 Additional content regarding LCM may be referenced at http://www.math.info/Arithmetic/LCM
