Calculate the LCM of 630,309,258,491

Given numbers are 630,309,258,491

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

The LCM of 630,309,258,491 is 1370022570.

Find LCM of 630,309,258,491 with Prime Factorization


2 630, 309, 258, 491
3 315, 309, 129, 491
105, 103, 43, 491

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

2 x 3 x 105 x 103 x 43 x 491 = 1370022570

Therefore, the lowest common multiple of 630,309,258,491 is 1370022570.

LCM Formula to Find Lowest Common Multiple of 630,309,258,491

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.

630 x 309 x 258 x 491 = 24660406260

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

309 : 1, 3, 103, 309

258 : 1, 2, 3, 6, 43, 86, 129, 258

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,309,258,491, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

309:3x 103

258:2x 3x 43

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.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 24660406260/(1x18)

LCM = 24660406260/18

LCM = 1370022570

Thus, we can understand that the LCM of 630,309,258,491 is 1370022570.
