Given numbers are 121,143,819,638

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

The LCM of 121,143,819,638 is 5747742.

Find LCM of 121,143,819,638 with Prime Factorization

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

11 x 13 x 11 x 1 x 63 x 58 = 5747742

Therefore, the lowest common multiple of 121,143,819,638 is 5747742.

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.

121 x 143 x 819 x 638 = 9041198166

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.

121 : 1, 11, 121

143 : 1, 11, 13, 143

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,143,819,638, is 1.

Now, the common factors can be found like this.

121:11x 11

143:11x 13

819:3x 3x 7x 13

638:2x 11x 29

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

11x 11x 13 = 1573

Therefore, the value for common factors is 1573.

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 = 9041198166/(1x1573)

LCM = 9041198166/1573

LCM = 5747742

Thus, we can understand that the LCM of 121,143,819,638 is 5747742.
