Given numbers are 128,223,868,704

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

The LCM of 128,223,868,704 is 68134528.

Find LCM of 128,223,868,704 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 2 x 223 x 217 x 11 = 68134528

Therefore, the lowest common multiple of 128,223,868,704 is 68134528.

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 223 x 868 x 704 = 17442439168

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

223 : 1, 223

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

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,223,868,704, is 1.

Now, the common factors can be found like this.

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

223:223

868:2x 2x 7x 31

704:2x 2x 2x 2x 2x 2x 11

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 2x 2x 2x 2x 2 = 256

Therefore, the value for common factors is 256.

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 = 17442439168/(1x256)

LCM = 17442439168/256

LCM = 68134528

Thus, we can understand that the LCM of 128,223,868,704 is 68134528.
