Given numbers are 268,661,407,642

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

The LCM of 268,661,407,642 is 23143854756.

Find LCM of 268,661,407,642 with Prime Factorization

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

2 x 134 x 661 x 407 x 321 = 23143854756

Therefore, the lowest common multiple of 268,661,407,642 is 23143854756.

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.

268 x 661 x 407 x 642 = 46287709512

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.

268 : 1, 2, 4, 67, 134, 268

661 : 1, 661

407 : 1, 11, 37, 407

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,661,407,642, is 1.

Now, the common factors can be found like this.

268:2x 2x 67

661:661

407:11x 37

642:2x 3x 107

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 = 46287709512/(1x2)

LCM = 46287709512/2

LCM = 23143854756

Thus, we can understand that the LCM of 268,661,407,642 is 23143854756.
