Given numbers are 437,622,311,21

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

The LCM of 437,622,311,21 is 5708094.

Find LCM of 437,622,311,21 with Prime Factorization

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

311 x 437 x 2 x 1 x 21 = 5708094

Therefore, the lowest common multiple of 437,622,311,21 is 5708094.

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.

437 x 622 x 311 x 21 = 1775217234

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.

437 : 1, 19, 23, 437

622 : 1, 2, 311, 622

311 : 1, 311

21 : 1, 3, 7, 21

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,622,311,21, is 1.

Now, the common factors can be found like this.

437:19x 23

622:2x 311

311:311

21:3x 7

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

311 = 311

Therefore, the value for common factors is 311.

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 = 1775217234/(1x311)

LCM = 1775217234/311

LCM = 5708094

Thus, we can understand that the LCM of 437,622,311,21 is 5708094.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 158, 447, 415, 29
