Given numbers are 145,29,620

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

The LCM of 145,29,620 is 17980.

Find LCM of 145,29,620 with Prime Factorization

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

5 x 29 x 1 x 1 x 124 = 17980

Therefore, the lowest common multiple of 145,29,620 is 17980.

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.

145 x 29 x 620 = 2607100

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.

145 : 1, 5, 29, 145

29 : 1, 29

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,29,620, is 1.

Now, the common factors can be found like this.

145:5x 29

29:29

620:2x 2x 5x 31

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

5x 29 = 145

Therefore, the value for common factors is 145.

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 = 2607100/(1x145)

LCM = 2607100/145

LCM = 17980

Thus, we can understand that the LCM of 145,29,620 is 17980.

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

• LCM of 332, 88, 112
• LCM of 602, 17, 579
