Given numbers are 857,225,474,390,520

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

The LCM of 857,225,474,390,520 is 1584250200.

Find LCM of 857,225,474,390,520 with Prime Factorization

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

2 x 3 x 5 x 13 x 857 x 15 x 79 x 1 x 4 = 1584250200

Therefore, the lowest common multiple of 857,225,474,390,520 is 1584250200.

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.

857 x 225 x 474 x 390 x 520 = 18535727340000

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.

857 : 1, 857

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

474 : 1, 2, 3, 6, 79, 158, 237, 474

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,225,474,390,520, is 1.

Now, the common factors can be found like this.

857:857

225:3x 3x 5x 5

474:2x 3x 79

390:2x 3x 5x 13

520:2x 2x 2x 5x 13

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 3x 3x 5x 5x 13 = 11700

Therefore, the value for common factors is 11700.

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 = 18535727340000/(1x11700)

LCM = 18535727340000/11700

LCM = 1584250200

Thus, we can understand that the LCM of 857,225,474,390,520 is 1584250200.
