Given numbers are 605,278,205,136

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

The LCM of 605,278,205,136 is 468913720.

Find LCM of 605,278,205,136 with Prime Factorization

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

2 x 5 x 121 x 139 x 41 x 68 = 468913720

Therefore, the lowest common multiple of 605,278,205,136 is 468913720.

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.

605 x 278 x 205 x 136 = 4689137200

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.

605 : 1, 5, 11, 55, 121, 605

278 : 1, 2, 139, 278

205 : 1, 5, 41, 205

136 : 1, 2, 4, 8, 17, 34, 68, 136

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,278,205,136, is 1.

Now, the common factors can be found like this.

605:5x 11x 11

278:2x 139

205:5x 41

136:2x 2x 2x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 4689137200/(1x10)

LCM = 4689137200/10

LCM = 468913720

Thus, we can understand that the LCM of 605,278,205,136 is 468913720.
