Given numbers are 424,207,390,121,844

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

The LCM of 424,207,390,121,844 is 145652312520.

Find LCM of 424,207,390,121,844 with Prime Factorization

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

2 x 2 x 3 x 106 x 69 x 65 x 121 x 211 = 145652312520

Therefore, the lowest common multiple of 424,207,390,121,844 is 145652312520.

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.

424 x 207 x 390 x 121 x 844 = 3495655500480

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

207 : 1, 3, 9, 23, 69, 207

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

121 : 1, 11, 121

844 : 1, 2, 4, 211, 422, 844

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,207,390,121,844, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

207:3x 3x 23

390:2x 3x 5x 13

121:11x 11

844:2x 2x 211

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 3495655500480/(1x24)

LCM = 3495655500480/24

LCM = 145652312520

Thus, we can understand that the LCM of 424,207,390,121,844 is 145652312520.
