Given numbers are 128,674,228,867

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

The LCM of 128,674,228,867 is 710579328.

Find LCM of 128,674,228,867 with Prime Factorization

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

2 x 2 x 3 x 32 x 337 x 19 x 289 = 710579328

Therefore, the lowest common multiple of 128,674,228,867 is 710579328.

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.

128 x 674 x 228 x 867 = 17053903872

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.

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

674 : 1, 2, 337, 674

228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,674,228,867, is 1.

Now, the common factors can be found like this.

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

674:2x 337

228:2x 2x 3x 19

867:3x 17x 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 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 17053903872/(1x24)

LCM = 17053903872/24

LCM = 710579328

Thus, we can understand that the LCM of 128,674,228,867 is 710579328.
