Calculate the LCM of 660,470,409

Given numbers are 660,470,409

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

The LCM of 660,470,409 is 12687180.

Find LCM of 660,470,409 with Prime Factorization


2 660, 470, 409
5 330, 235, 409
66, 47, 409

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

2 x 5 x 66 x 47 x 409 = 12687180

Therefore, the lowest common multiple of 660,470,409 is 12687180.

LCM Formula to Find Lowest Common Multiple of 660,470,409

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.

660 x 470 x 409 = 126871800

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

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

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,470,409, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

470:2x 5x 47

409:409

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 126871800/(1x10)

LCM = 126871800/10

LCM = 12687180

Thus, we can understand that the LCM of 660,470,409 is 12687180.
