Given numbers are 638,105,458,877

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

The LCM of 638,105,458,877 is 13453802670.

Find LCM of 638,105,458,877 with Prime Factorization

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

2 x 319 x 105 x 229 x 877 = 13453802670

Therefore, the lowest common multiple of 638,105,458,877 is 13453802670.

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.

638 x 105 x 458 x 877 = 26907605340

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.

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

105 : 1, 3, 5, 7, 15, 21, 35, 105

458 : 1, 2, 229, 458

877 : 1, 877

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,105,458,877, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

105:3x 5x 7

458:2x 229

877:877

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

2 = 2

Therefore, the value for common factors is 2.

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 = 26907605340/(1x2)

LCM = 26907605340/2

LCM = 13453802670

Thus, we can understand that the LCM of 638,105,458,877 is 13453802670.
