Given numbers are 649,638,630,311

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

The LCM of 649,638,630,311 is 3687598530.

Find LCM of 649,638,630,311 with Prime Factorization

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

2 x 11 x 59 x 29 x 315 x 311 = 3687598530

Therefore, the lowest common multiple of 649,638,630,311 is 3687598530.

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 638 x 630 x 311 = 81127167660

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

311 : 1, 311

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,638,630,311, is 1.

Now, the common factors can be found like this.

649:11x 59

638:2x 11x 29

630:2x 3x 3x 5x 7

311:311

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 81127167660/(1x22)

LCM = 81127167660/22

LCM = 3687598530

Thus, we can understand that the LCM of 649,638,630,311 is 3687598530.
