Given numbers are 649,390,579,912,381

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

The LCM of 649,390,579,912,381 is 943004839920.

Find LCM of 649,390,579,912,381 with Prime Factorization

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

2 x 3 x 649 x 65 x 193 x 152 x 127 = 943004839920

Therefore, the lowest common multiple of 649,390,579,912,381 is 943004839920.

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 390 x 579 x 912 x 381 = 50922261355680

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

579 : 1, 3, 193, 579

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,390,579,912,381, is 1.

Now, the common factors can be found like this.

649:11x 59

390:2x 3x 5x 13

579:3x 193

912:2x 2x 2x 2x 3x 19

381:3x 127

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 50922261355680/(1x54)

LCM = 50922261355680/54

LCM = 943004839920

Thus, we can understand that the LCM of 649,390,579,912,381 is 943004839920.
