Given numbers are 817,388,133,969

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

The LCM of 817,388,133,969 is 113167572.

Find LCM of 817,388,133,969 with Prime Factorization

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

19 x 43 x 388 x 7 x 51 = 113167572

Therefore, the lowest common multiple of 817,388,133,969 is 113167572.

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.

817 x 388 x 133 x 969 = 40853493492

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.

817 : 1, 19, 43, 817

388 : 1, 2, 4, 97, 194, 388

133 : 1, 7, 19, 133

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 817,388,133,969, is 1.

Now, the common factors can be found like this.

817:19x 43

388:2x 2x 97

133:7x 19

969:3x 17x 19

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

19x 19 = 361

Therefore, the value for common factors is 361.

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 = 40853493492/(1x361)

LCM = 40853493492/361

LCM = 113167572

Thus, we can understand that the LCM of 817,388,133,969 is 113167572.
