Given numbers are 217,726,660,936,915

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

The LCM of 217,726,660,936,915 is 7495848360.

Find LCM of 217,726,660,936,915 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 217 x 1 x 11 x 78 x 61 = 7495848360

Therefore, the lowest common multiple of 217,726,660,936,915 is 7495848360.

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.

217 x 726 x 660 x 936 x 915 = 89050678516800

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.

217 : 1, 7, 31, 217

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,726,660,936,915, is 1.

Now, the common factors can be found like this.

217:7x 31

726:2x 3x 11x 11

660:2x 2x 3x 5x 11

936:2x 2x 2x 3x 3x 13

915:3x 5x 61

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 3x 3x 3x 5x 11 = 11880

Therefore, the value for common factors is 11880.

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 = 89050678516800/(1x11880)

LCM = 89050678516800/11880

LCM = 7495848360

Thus, we can understand that the LCM of 217,726,660,936,915 is 7495848360.
