Given numbers are 117,20,611

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

The LCM of 117,20,611 is 109980.

Find LCM of 117,20,611 with Prime Factorization

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

13 x 9 x 20 x 47 = 109980

Therefore, the lowest common multiple of 117,20,611 is 109980.

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.

117 x 20 x 611 = 1429740

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.

117 : 1, 3, 9, 13, 39, 117

20 : 1, 2, 4, 5, 10, 20

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,20,611, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

20:2x 2x 5

611:13x 47

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 = 1429740/(1x13)

LCM = 1429740/13

LCM = 109980

Thus, we can understand that the LCM of 117,20,611 is 109980.

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

• LCM of 699, 79, 367
• LCM of 978, 71, 827
