Given numbers are 517,55,172

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

The LCM of 517,55,172 is 444620.

Find LCM of 517,55,172 with Prime Factorization

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

11 x 47 x 5 x 172 = 444620

Therefore, the lowest common multiple of 517,55,172 is 444620.

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.

517 x 55 x 172 = 4890820

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.

517 : 1, 11, 47, 517

55 : 1, 5, 11, 55

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,55,172, is 1.

Now, the common factors can be found like this.

517:11x 47

55:5x 11

172:2x 2x 43

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

11 = 11

Therefore, the value for common factors is 11.

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 = 4890820/(1x11)

LCM = 4890820/11

LCM = 444620

Thus, we can understand that the LCM of 517,55,172 is 444620.

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

• LCM of 637, 99, 957
• LCM of 666, 26, 743
