Given numbers are 287,121,133,404

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

The LCM of 287,121,133,404 is 266564452.

Find LCM of 287,121,133,404 with Prime Factorization

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

7 x 41 x 121 x 19 x 404 = 266564452

Therefore, the lowest common multiple of 287,121,133,404 is 266564452.

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.

287 x 121 x 133 x 404 = 1865951164

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.

287 : 1, 7, 41, 287

121 : 1, 11, 121

133 : 1, 7, 19, 133

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,121,133,404, is 1.

Now, the common factors can be found like this.

287:7x 41

121:11x 11

133:7x 19

404:2x 2x 101

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

7 = 7

Therefore, the value for common factors is 7.

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 = 1865951164/(1x7)

LCM = 1865951164/7

LCM = 266564452

Thus, we can understand that the LCM of 287,121,133,404 is 266564452.
