Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 3 x 5 x 17 x 137 x 1 x 13 x 4 = 14532960

Therefore, the lowest common multiple of 685,408,663,480 is 14532960.

LCM Formula to Find Lowest Common Multiple of 685,408,663,480

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.

685 x 408 x 663 x 480 = 88941715200

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.

685 : 1, 5, 137, 685

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

663 : 1, 3, 13, 17, 39, 51, 221, 663

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,408,663,480, is 1.

Now, the common factors can be found like this.

685:5x 137

408:2x 2x 2x 3x 17

663:3x 13x 17

480:2x 2x 2x 2x 2x 3x 5

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 5x 17 = 6120

Therefore, the value for common factors is 6120.

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 = 88941715200/(1x6120)

LCM = 88941715200/6120

LCM = 14532960

Thus, we can understand that the LCM of 685,408,663,480 is 14532960.
