Given numbers are 649,352,840,124

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

The LCM of 649,352,840,124 is 67599840.

Find LCM of 649,352,840,124 with Prime Factorization

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

2 x 2 x 2 x 11 x 59 x 4 x 105 x 31 = 67599840

Therefore, the lowest common multiple of 649,352,840,124 is 67599840.

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 352 x 840 x 124 = 23795143680

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

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

124 : 1, 2, 4, 31, 62, 124

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,352,840,124, is 1.

Now, the common factors can be found like this.

649:11x 59

352:2x 2x 2x 2x 2x 11

840:2x 2x 2x 3x 5x 7

124:2x 2x 31

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 2x 11 = 352

Therefore, the value for common factors is 352.

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 = 23795143680/(1x352)

LCM = 23795143680/352

LCM = 67599840

Thus, we can understand that the LCM of 649,352,840,124 is 67599840.
