Given numbers are 662,21,356

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

The LCM of 662,21,356 is 2474556.

Find LCM of 662,21,356 with Prime Factorization

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

2 x 331 x 21 x 178 = 2474556

Therefore, the lowest common multiple of 662,21,356 is 2474556.

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.

662 x 21 x 356 = 4949112

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.

662 : 1, 2, 331, 662

21 : 1, 3, 7, 21

356 : 1, 2, 4, 89, 178, 356

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,21,356, is 1.

Now, the common factors can be found like this.

662:2x 331

21:3x 7

356:2x 2x 89

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

2 = 2

Therefore, the value for common factors is 2.

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 = 4949112/(1x2)

LCM = 4949112/2

LCM = 2474556

Thus, we can understand that the LCM of 662,21,356 is 2474556.

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

• LCM of 510, 35, 639
• LCM of 782, 82, 291
