(39 x 26) + (39 x 13) = 39 x 39 = 1521
1014 / 39 = 26
13. 13 x 2 = 26 13 x 3 = 39 13 x 4 = 52
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.
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.
