Given numbers are 638,497,440,880

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

The LCM of 638,497,440,880 is 12683440.

Find LCM of 638,497,440,880 with Prime Factorization

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

2 x 2 x 2 x 5 x 11 x 29 x 497 x 1 x 2 = 12683440

Therefore, the lowest common multiple of 638,497,440,880 is 12683440.

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.

638 x 497 x 440 x 880 = 122775699200

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.

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

497 : 1, 7, 71, 497

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

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,497,440,880, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

497:7x 71

440:2x 2x 2x 5x 11

880:2x 2x 2x 2x 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.

2x 2x 2x 2x 5x 11x 11 = 9680

Therefore, the value for common factors is 9680.

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 = 122775699200/(1x9680)

LCM = 122775699200/9680

LCM = 12683440

Thus, we can understand that the LCM of 638,497,440,880 is 12683440.
