Given numbers are 441,161,491

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

The LCM of 441,161,491 is 4980213.

Find LCM of 441,161,491 with Prime Factorization

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

7 x 63 x 23 x 491 = 4980213

Therefore, the lowest common multiple of 441,161,491 is 4980213.

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.

441 x 161 x 491 = 34861491

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.

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

161 : 1, 7, 23, 161

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,161,491, is 1.

Now, the common factors can be found like this.

441:3x 3x 7x 7

161:7x 23

491:491

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

7 = 7

Therefore, the value for common factors is 7.

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 = 34861491/(1x7)

LCM = 34861491/7

LCM = 4980213

Thus, we can understand that the LCM of 441,161,491 is 4980213.

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

• LCM of 195, 227, 617
• LCM of 429, 421, 233
• LCM of 730, 129, 768
