Given numbers are 140,821,458,209,442

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

The LCM of 140,821,458,209,442 is 1215752678140.

Find LCM of 140,821,458,209,442 with Prime Factorization

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

2 x 70 x 821 x 229 x 209 x 221 = 1215752678140

Therefore, the lowest common multiple of 140,821,458,209,442 is 1215752678140.

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.

140 x 821 x 458 x 209 x 442 = 4863010712560

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

821 : 1, 821

458 : 1, 2, 229, 458

209 : 1, 11, 19, 209

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,821,458,209,442, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

821:821

458:2x 229

209:11x 19

442:2x 13x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4863010712560/(1x4)

LCM = 4863010712560/4

LCM = 1215752678140

Thus, we can understand that the LCM of 140,821,458,209,442 is 1215752678140.
