LCM Formula to Find Lowest Common Multiple of 672,736,309,448

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.

672 x 736 x 309 x 448 = 68467359744

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

309 : 1, 3, 103, 309

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,736,309,448, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

736:2x 2x 2x 2x 2x 23

309:3x 103

448:2x 2x 2x 2x 2x 2x 7

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 2x 2x 2x 2x 2x 2x 2x 3x 7 = 21504

Therefore, the value for common factors is 21504.

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 = 68467359744/(1x21504)

LCM = 68467359744/21504

LCM = 3183936

Thus, we can understand that the LCM of 672,736,309,448 is 3183936.
