Given numbers are 907,618,451,638

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

The LCM of 907,618,451,638 is 7331119554.

Find LCM of 907,618,451,638 with Prime Factorization

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

2 x 11 x 907 x 309 x 41 x 29 = 7331119554

Therefore, the lowest common multiple of 907,618,451,638 is 7331119554.

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.

907 x 618 x 451 x 638 = 161284630188

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.

907 : 1, 907

618 : 1, 2, 3, 6, 103, 206, 309, 618

451 : 1, 11, 41, 451

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,618,451,638, is 1.

Now, the common factors can be found like this.

907:907

618:2x 3x 103

451:11x 41

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 161284630188/(1x22)

LCM = 161284630188/22

LCM = 7331119554

Thus, we can understand that the LCM of 907,618,451,638 is 7331119554.
