Given numbers are 287,358,872,654

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

The LCM of 287,358,872,654 is 134391768.

Find LCM of 287,358,872,654 with Prime Factorization

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

2 x 109 x 287 x 179 x 4 x 3 = 134391768

Therefore, the lowest common multiple of 287,358,872,654 is 134391768.

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.

287 x 358 x 872 x 654 = 58594810848

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.

287 : 1, 7, 41, 287

358 : 1, 2, 179, 358

872 : 1, 2, 4, 8, 109, 218, 436, 872

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,358,872,654, is 1.

Now, the common factors can be found like this.

287:7x 41

358:2x 179

872:2x 2x 2x 109

654:2x 3x 109

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 109 = 436

Therefore, the value for common factors is 436.

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 = 58594810848/(1x436)

LCM = 58594810848/436

LCM = 134391768

Thus, we can understand that the LCM of 287,358,872,654 is 134391768.
