Given numbers are 821,699,417

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

The LCM of 821,699,417 is 79769181.

Find LCM of 821,699,417 with Prime Factorization

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

3 x 821 x 233 x 139 = 79769181

Therefore, the lowest common multiple of 821,699,417 is 79769181.

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.

821 x 699 x 417 = 239307543

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.

821 : 1, 821

699 : 1, 3, 233, 699

417 : 1, 3, 139, 417

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,699,417, is 1.

Now, the common factors can be found like this.

821:821

699:3x 233

417:3x 139

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

3 = 3

Therefore, the value for common factors is 3.

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 = 239307543/(1x3)

LCM = 239307543/3

LCM = 79769181

Thus, we can understand that the LCM of 821,699,417 is 79769181.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 195, 936, 290
• LCM of 397, 975, 916
