Given numbers are 173,784,819,210

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

The LCM of 173,784,819,210 is 79344720.

Find LCM of 173,784,819,210 with Prime Factorization

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

2 x 3 x 7 x 173 x 56 x 39 x 5 = 79344720

Therefore, the lowest common multiple of 173,784,819,210 is 79344720.

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.

173 x 784 x 819 x 210 = 23327347680

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.

173 : 1, 173

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,784,819,210, is 1.

Now, the common factors can be found like this.

173:173

784:2x 2x 2x 2x 7x 7

819:3x 3x 7x 13

210:2x 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 3x 7x 7 = 294

Therefore, the value for common factors is 294.

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 = 23327347680/(1x294)

LCM = 23327347680/294

LCM = 79344720

Thus, we can understand that the LCM of 173,784,819,210 is 79344720.
