(39 x 26) + (39 x 13) = 39 x 39 = 1521
1014 / 39 = 26
The GCF is 13.
39 x 26 = 1024
There can be no greatest common denominator. Suppose x is the greatest common denominator. That requires that 39 divides x, 26 divides x and x is the greatest such number. But 39 will divide 2x and 26 will divide 2x and 2x is greater than x. So x could not have been a GCD.
The Least Common Multiple of the above is 13. 13 is prime, therefore it the LCM by default.
To find the least common multiple (LCM) of 26, 13, and 39, we first need to factorize each number into its prime factors. 26 = 2 x 13 13 = 13 39 = 3 x 13 Then, we identify the highest power of each prime factor that appears in any of the factorizations. In this case, the LCM is 2 x 3 x 13 = 78. Therefore, the least common multiple of 26, 13, and 39 is 78.
x 78, 2 x 39, 3 x 26, 6 x 13, 13 x 6, 26 x 3, 39 x 2, 78 x 1 = 78
78 = 1 x 78, 2 x 39, 3 x 26, 6 x 13, 13 x 6, 26 x 3, 39 x 2, 78 x 1.
1 x 78, 2 x 39, 3 x 26, 6 x 13, 13 x 6, 26 x 3, 39 x 2, 78 x 1
6x 13 =78 2 x 39 = 78 13 x 6 = 78 3 x 26 = 78 So the answer is 78.
1 x 78, 2 x 39, 3 x 26, 6 x 13.
