Given numbers are 47,84,213

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

The LCM of 47,84,213 is 280308.

Find LCM of 47,84,213 with Prime Factorization

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

3 x 47 x 28 x 71 = 280308

Therefore, the lowest common multiple of 47,84,213 is 280308.

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.

47 x 84 x 213 = 840924

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.

47 : 1, 47

84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

213 : 1, 3, 71, 213

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 47,84,213, is 1.

Now, the common factors can be found like this.

47:47

84:2x 2x 3x 7

213:3x 71

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

3 = 3

Therefore, the value for common factors is 3.

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 = 840924/(1x3)

LCM = 840924/3

LCM = 280308

Thus, we can understand that the LCM of 47,84,213 is 280308.

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

• LCM of 39, 40, 777
• LCM of 36, 71, 499
