Given numbers are 654,828,458,990

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

The LCM of 654,828,458,990 is 1136723940.

Find LCM of 654,828,458,990 with Prime Factorization

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

2 x 3 x 3 x 109 x 46 x 229 x 55 = 1136723940

Therefore, the lowest common multiple of 654,828,458,990 is 1136723940.

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.

654 x 828 x 458 x 990 = 245532371040

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

458 : 1, 2, 229, 458

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,828,458,990, is 2.

Now, the common factors can be found like this.

654:2x 3x 109

828:2x 2x 3x 3x 23

458:2x 229

990:2x 3x 3x 5x 11

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

2x 2x 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 245532371040/(2x108)

LCM = 245532371040/216

LCM = 1136723940

Thus, we can understand that the LCM of 654,828,458,990 is 1136723940.
