Given numbers are 331,232,213,145

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

The LCM of 331,232,213,145 is 81783480.

Find LCM of 331,232,213,145 with Prime Factorization

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

29 x 331 x 8 x 213 x 5 = 81783480

Therefore, the lowest common multiple of 331,232,213,145 is 81783480.

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.

331 x 232 x 213 x 145 = 2371720920

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.

331 : 1, 331

232 : 1, 2, 4, 8, 29, 58, 116, 232

213 : 1, 3, 71, 213

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,232,213,145, is 1.

Now, the common factors can be found like this.

331:331

232:2x 2x 2x 29

213:3x 71

145:5x 29

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

29 = 29

Therefore, the value for common factors is 29.

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 = 2371720920/(1x29)

LCM = 2371720920/29

LCM = 81783480

Thus, we can understand that the LCM of 331,232,213,145 is 81783480.
