Given numbers are 862,180,220,439,840

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 862,180,220,439,840 is 5244873480.

Find LCM of 862,180,220,439,840 with Prime Factorization

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

2 x 2 x 3 x 5 x 431 x 3 x 11 x 439 x 14 = 5244873480

Therefore, the lowest common multiple of 862,180,220,439,840 is 5244873480.

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.

862 x 180 x 220 x 439 x 840 = 12587696352000

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.

862 : 1, 2, 431, 862

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

439 : 1, 439

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,180,220,439,840, is 1.

Now, the common factors can be found like this.

862:2x 431

180:2x 2x 3x 3x 5

220:2x 2x 5x 11

439:439

840:2x 2x 2x 3x 5x 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 3x 5x 5 = 2400

Therefore, the value for common factors is 2400.

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 = 12587696352000/(1x2400)

LCM = 12587696352000/2400

LCM = 5244873480

Thus, we can understand that the LCM of 862,180,220,439,840 is 5244873480.
