LCM Formula to Find Lowest Common Multiple of 912,138,842,621,518

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

912 x 138 x 842 x 621 x 518 = 34088459561856

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

138 : 1, 2, 3, 6, 23, 46, 69, 138

842 : 1, 2, 421, 842

621 : 1, 3, 9, 23, 27, 69, 207, 621

518 : 1, 2, 7, 14, 37, 74, 259, 518

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,138,842,621,518, is 1.

Now, the common factors can be found like this.

912:2x 2x 2x 2x 3x 19

138:2x 3x 23

842:2x 421

621:3x 3x 3x 23

518:2x 7x 37

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3x 23 = 1656

Therefore, the value for common factors is 1656.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 34088459561856/(1x1656)

LCM = 34088459561856/1656

LCM = 20584818576

Thus, we can understand that the LCM of 912,138,842,621,518 is 20584818576.
