Given numbers are 416,788,490,684,781

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

The LCM of 416,788,490,684,781 is 2681469030240.

Find LCM of 416,788,490,684,781 with Prime Factorization

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

2 x 2 x 104 x 197 x 245 x 171 x 781 = 2681469030240

Therefore, the lowest common multiple of 416,788,490,684,781 is 2681469030240.

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.

416 x 788 x 490 x 684 x 781 = 85807008967680

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.

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

788 : 1, 2, 4, 197, 394, 788

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 416,788,490,684,781, is 1.

Now, the common factors can be found like this.

416:2x 2x 2x 2x 2x 13

788:2x 2x 197

490:2x 5x 7x 7

684:2x 2x 3x 3x 19

781:11x 71

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 2 = 32

Therefore, the value for common factors is 32.

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 = 85807008967680/(1x32)

LCM = 85807008967680/32

LCM = 2681469030240

Thus, we can understand that the LCM of 416,788,490,684,781 is 2681469030240.
