Given numbers are 119,638,643,440

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

The LCM of 119,638,643,440 is 976356920.

Find LCM of 119,638,643,440 with Prime Factorization

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

2 x 11 x 119 x 29 x 643 x 20 = 976356920

Therefore, the lowest common multiple of 119,638,643,440 is 976356920.

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.

119 x 638 x 643 x 440 = 21479852240

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.

119 : 1, 7, 17, 119

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

643 : 1, 643

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 119,638,643,440, is 1.

Now, the common factors can be found like this.

119:7x 17

638:2x 11x 29

643:643

440:2x 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 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 = 21479852240/(1x22)

LCM = 21479852240/22

LCM = 976356920

Thus, we can understand that the LCM of 119,638,643,440 is 976356920.
