Given numbers are 128,417,742,322

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

The LCM of 128,417,742,322 is 455457408.

Find LCM of 128,417,742,322 with Prime Factorization

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

2 x 7 x 64 x 417 x 53 x 23 = 455457408

Therefore, the lowest common multiple of 128,417,742,322 is 455457408.

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 417 x 742 x 322 = 12752807424

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

417 : 1, 3, 139, 417

742 : 1, 2, 7, 14, 53, 106, 371, 742

322 : 1, 2, 7, 14, 23, 46, 161, 322

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,417,742,322, is 1.

Now, the common factors can be found like this.

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

417:3x 139

742:2x 7x 53

322:2x 7x 23

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 7 = 28

Therefore, the value for common factors is 28.

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 = 12752807424/(1x28)

LCM = 12752807424/28

LCM = 455457408

Thus, we can understand that the LCM of 128,417,742,322 is 455457408.
