Given numbers are 642,299,667,556,345

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

The LCM of 642,299,667,556,345 is 7737826980.

Find LCM of 642,299,667,556,345 with Prime Factorization

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

2 x 3 x 23 x 107 x 13 x 29 x 278 x 5 = 7737826980

Therefore, the lowest common multiple of 642,299,667,556,345 is 7737826980.

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.

642 x 299 x 667 x 556 x 345 = 24559862834520

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.

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

299 : 1, 13, 23, 299

667 : 1, 23, 29, 667

556 : 1, 2, 4, 139, 278, 556

345 : 1, 3, 5, 15, 23, 69, 115, 345

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,299,667,556,345, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

299:13x 23

667:23x 29

556:2x 2x 139

345:3x 5x 23

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

2x 3x 23x 23 = 3174

Therefore, the value for common factors is 3174.

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 = 24559862834520/(1x3174)

LCM = 24559862834520/3174

LCM = 7737826980

Thus, we can understand that the LCM of 642,299,667,556,345 is 7737826980.
