Given numbers are 649,247,660

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

The LCM of 649,247,660 is 9618180.

Find LCM of 649,247,660 with Prime Factorization

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

11 x 59 x 247 x 60 = 9618180

Therefore, the lowest common multiple of 649,247,660 is 9618180.

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.

649 x 247 x 660 = 105799980

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.

649 : 1, 11, 59, 649

247 : 1, 13, 19, 247

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,247,660, is 1.

Now, the common factors can be found like this.

649:11x 59

247:13x 19

660:2x 2x 3x 5x 11

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 = 105799980/(1x11)

LCM = 105799980/11

LCM = 9618180

Thus, we can understand that the LCM of 649,247,660 is 9618180.

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

• LCM of 707, 587, 495
