Given numbers are 790,221,819

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

The LCM of 790,221,819 is 10999170.

Find LCM of 790,221,819 with Prime Factorization

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

13 x 790 x 17 x 63 = 10999170

Therefore, the lowest common multiple of 790,221,819 is 10999170.

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.

790 x 221 x 819 = 142989210

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

221 : 1, 13, 17, 221

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,221,819, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

221:13x 17

819:3x 3x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 142989210/(1x13)

LCM = 142989210/13

LCM = 10999170

Thus, we can understand that the LCM of 790,221,819 is 10999170.
