Given numbers are 407,868,366,721

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

The LCM of 407,868,366,721 is 6658899324.

Find LCM of 407,868,366,721 with Prime Factorization

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

2 x 7 x 407 x 62 x 183 x 103 = 6658899324

Therefore, the lowest common multiple of 407,868,366,721 is 6658899324.

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.

407 x 868 x 366 x 721 = 93224590536

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.

407 : 1, 11, 37, 407

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

366 : 1, 2, 3, 6, 61, 122, 183, 366

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,868,366,721, is 1.

Now, the common factors can be found like this.

407:11x 37

868:2x 2x 7x 31

366:2x 3x 61

721:7x 103

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 93224590536/(1x14)

LCM = 93224590536/14

LCM = 6658899324

Thus, we can understand that the LCM of 407,868,366,721 is 6658899324.
