Given numbers are 351,340,911,172

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

The LCM of 351,340,911,172 is 4674905820.

Find LCM of 351,340,911,172 with Prime Factorization

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

2 x 2 x 351 x 85 x 911 x 43 = 4674905820

Therefore, the lowest common multiple of 351,340,911,172 is 4674905820.

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.

351 x 340 x 911 x 172 = 18699623280

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.

351 : 1, 3, 9, 13, 27, 39, 117, 351

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

911 : 1, 911

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,340,911,172, is 1.

Now, the common factors can be found like this.

351:3x 3x 3x 13

340:2x 2x 5x 17

911:911

172:2x 2x 43

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 = 18699623280/(1x4)

LCM = 18699623280/4

LCM = 4674905820

Thus, we can understand that the LCM of 351,340,911,172 is 4674905820.
