Given numbers are 906,684,863,420

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

The LCM of 906,684,863,420 is 3119693220.

Find LCM of 906,684,863,420 with Prime Factorization

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

2 x 2 x 3 x 151 x 57 x 863 x 35 = 3119693220

Therefore, the lowest common multiple of 906,684,863,420 is 3119693220.

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.

906 x 684 x 863 x 420 = 224617911840

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.

906 : 1, 2, 3, 6, 151, 302, 453, 906

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

863 : 1, 863

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,684,863,420, is 1.

Now, the common factors can be found like this.

906:2x 3x 151

684:2x 2x 3x 3x 19

863:863

420:2x 2x 3x 5x 7

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 3 = 72

Therefore, the value for common factors is 72.

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 = 224617911840/(1x72)

LCM = 224617911840/72

LCM = 3119693220

Thus, we can understand that the LCM of 906,684,863,420 is 3119693220.
