Given numbers are 668,442,407,632

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

The LCM of 668,442,407,632 is 9493366168.

Find LCM of 668,442,407,632 with Prime Factorization

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

2 x 2 x 167 x 221 x 407 x 158 = 9493366168

Therefore, the lowest common multiple of 668,442,407,632 is 9493366168.

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.

668 x 442 x 407 x 632 = 75946929344

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.

668 : 1, 2, 4, 167, 334, 668

442 : 1, 2, 13, 17, 26, 34, 221, 442

407 : 1, 11, 37, 407

632 : 1, 2, 4, 8, 79, 158, 316, 632

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,442,407,632, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

442:2x 13x 17

407:11x 37

632:2x 2x 2x 79

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 2 = 8

Therefore, the value for common factors is 8.

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 = 75946929344/(1x8)

LCM = 75946929344/8

LCM = 9493366168

Thus, we can understand that the LCM of 668,442,407,632 is 9493366168.
