Given numbers are 611,213,221

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

The LCM of 611,213,221 is 2212431.

Find LCM of 611,213,221 with Prime Factorization

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

13 x 47 x 213 x 17 = 2212431

Therefore, the lowest common multiple of 611,213,221 is 2212431.

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.

611 x 213 x 221 = 28761603

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.

611 : 1, 13, 47, 611

213 : 1, 3, 71, 213

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,213,221, is 1.

Now, the common factors can be found like this.

611:13x 47

213:3x 71

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 28761603/(1x13)

LCM = 28761603/13

LCM = 2212431

Thus, we can understand that the LCM of 611,213,221 is 2212431.

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

• LCM of 174, 754, 653
