Given numbers are 649,440,671

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

The LCM of 649,440,671 is 1583560.

Find LCM of 649,440,671 with Prime Factorization

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

11 x 59 x 40 x 61 = 1583560

Therefore, the lowest common multiple of 649,440,671 is 1583560.

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 440 x 671 = 191610760

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

671 : 1, 11, 61, 671

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,440,671, is 11.

Now, the common factors can be found like this.

649:11x 59

440:2x 2x 2x 5x 11

671:11x 61

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 = 191610760/(11x11)

LCM = 191610760/121

LCM = 1583560

Thus, we can understand that the LCM of 649,440,671 is 1583560.
