Given numbers are 134,642,422,280

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

The LCM of 134,642,422,280 is 1270633560.

Find LCM of 134,642,422,280 with Prime Factorization

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

2 x 67 x 321 x 211 x 140 = 1270633560

Therefore, the lowest common multiple of 134,642,422,280 is 1270633560.

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.

134 x 642 x 422 x 280 = 10165068480

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.

134 : 1, 2, 67, 134

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

422 : 1, 2, 211, 422

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 134,642,422,280, is 2.

Now, the common factors can be found like this.

134:2x 67

642:2x 3x 107

422:2x 211

280:2x 2x 2x 5x 7

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 10165068480/(2x4)

LCM = 10165068480/8

LCM = 1270633560

Thus, we can understand that the LCM of 134,642,422,280 is 1270633560.
