LCM Formula to Find Lowest Common Multiple of 391,414,185,840,540

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.

391 x 414 x 185 x 840 x 540 = 13583818584000

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.

391 : 1, 17, 23, 391

414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414

185 : 1, 5, 37, 185

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,414,185,840,540, is 1.

Now, the common factors can be found like this.

391:17x 23

414:2x 3x 3x 23

185:5x 37

840:2x 2x 2x 3x 5x 7

540:2x 2x 3x 3x 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 3x 5x 5x 23 = 124200

Therefore, the value for common factors is 124200.

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 = 13583818584000/(1x124200)

LCM = 13583818584000/124200

LCM = 109370520

Thus, we can understand that the LCM of 391,414,185,840,540 is 109370520.
