Given numbers are 619,507,639,149,990

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

The LCM of 619,507,639,149,990 is 1095612971310.

Find LCM of 619,507,639,149,990 with Prime Factorization

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

3 x 3 x 619 x 169 x 71 x 149 x 110 = 1095612971310

Therefore, the lowest common multiple of 619,507,639,149,990 is 1095612971310.

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.

619 x 507 x 639 x 149 x 990 = 29581550225370

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.

619 : 1, 619

507 : 1, 3, 13, 39, 169, 507

639 : 1, 3, 9, 71, 213, 639

149 : 1, 149

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,507,639,149,990, is 1.

Now, the common factors can be found like this.

619:619

507:3x 13x 13

639:3x 3x 71

149:149

990:2x 3x 3x 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.

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 29581550225370/(1x27)

LCM = 29581550225370/27

LCM = 1095612971310

Thus, we can understand that the LCM of 619,507,639,149,990 is 1095612971310.
