Given numbers are 722,128,867,785,618

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

The LCM of 722,128,867,785,618 is 3239240177280.

Find LCM of 722,128,867,785,618 with Prime Factorization

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

2 x 3 x 361 x 64 x 289 x 785 x 103 = 3239240177280

Therefore, the lowest common multiple of 722,128,867,785,618 is 3239240177280.

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.

722 x 128 x 867 x 785 x 618 = 38870882127360

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.

722 : 1, 2, 19, 38, 361, 722

128 : 1, 2, 4, 8, 16, 32, 64, 128

867 : 1, 3, 17, 51, 289, 867

785 : 1, 5, 157, 785

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,128,867,785,618, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

128:2x 2x 2x 2x 2x 2x 2

867:3x 17x 17

785:5x 157

618:2x 3x 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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 38870882127360/(1x12)

LCM = 38870882127360/12

LCM = 3239240177280

Thus, we can understand that the LCM of 722,128,867,785,618 is 3239240177280.
