Given numbers are 657,717,491

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

The LCM of 657,717,491 is 77098293.

Find LCM of 657,717,491 with Prime Factorization

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

3 x 219 x 239 x 491 = 77098293

Therefore, the lowest common multiple of 657,717,491 is 77098293.

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.

657 x 717 x 491 = 231294879

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.

657 : 1, 3, 9, 73, 219, 657

717 : 1, 3, 239, 717

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,717,491, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

717:3x 239

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.

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 = 231294879/(1x3)

LCM = 231294879/3

LCM = 77098293

Thus, we can understand that the LCM of 657,717,491 is 77098293.

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

• LCM of 865, 246, 960
• LCM of 913, 775, 556
