Given numbers are 65,87,29,470

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

The LCM of 65,87,29,470 is 531570.

Find LCM of 65,87,29,470 with Prime Factorization

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

5 x 29 x 13 x 3 x 1 x 94 = 531570

Therefore, the lowest common multiple of 65,87,29,470 is 531570.

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.

65 x 87 x 29 x 470 = 77077650

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.

65 : 1, 5, 13, 65

87 : 1, 3, 29, 87

29 : 1, 29

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 65,87,29,470, is 1.

Now, the common factors can be found like this.

65:5x 13

87:3x 29

29:29

470:2x 5x 47

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 = 77077650/(1x145)

LCM = 77077650/145

LCM = 531570

Thus, we can understand that the LCM of 65,87,29,470 is 531570.

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