Given numbers are 715,821,305

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

The LCM of 715,821,305 is 35807915.

Find LCM of 715,821,305 with Prime Factorization

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

5 x 143 x 821 x 61 = 35807915

Therefore, the lowest common multiple of 715,821,305 is 35807915.

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.

715 x 821 x 305 = 179039575

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

821 : 1, 821

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,821,305, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

821:821

305:5x 61

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

5 = 5

Therefore, the value for common factors is 5.

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 = 179039575/(1x5)

LCM = 179039575/5

LCM = 35807915

Thus, we can understand that the LCM of 715,821,305 is 35807915.

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

• LCM of 252, 178, 570
• LCM of 464, 100, 927
