17 68, 253, 437, 221
23 4, 253, 437, 13
4, 11, 19, 13

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

2 x 3 x 17 x 23 x 4 x 11 x 19 x 13 = 25496328

Therefore, the lowest common multiple of 408,759,437,442 is 25496328.

LCM Formula to Find Lowest Common Multiple of 408,759,437,442

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.

408 x 759 x 437 x 442 = 59814385488

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.

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

759 : 1, 3, 11, 23, 33, 69, 253, 759

437 : 1, 19, 23, 437

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,759,437,442, is 1.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

759:3x 11x 23

437:19x 23

442:2x 13x 17

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

2x 3x 17x 23 = 2346

Therefore, the value for common factors is 2346.

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 = 59814385488/(1x2346)

LCM = 59814385488/2346

LCM = 25496328

Thus, we can understand that the LCM of 408,759,437,442 is 25496328.
