Given numbers are 989,913,121,289

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

The LCM of 989,913,121,289 is 2870500303.

Find LCM of 989,913,121,289 with Prime Factorization

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

11 x 989 x 83 x 11 x 289 = 2870500303

Therefore, the lowest common multiple of 989,913,121,289 is 2870500303.

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.

989 x 913 x 121 x 289 = 31575503333

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.

989 : 1, 23, 43, 989

913 : 1, 11, 83, 913

121 : 1, 11, 121

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,913,121,289, is 1.

Now, the common factors can be found like this.

989:23x 43

913:11x 83

121:11x 11

289:17x 17

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

11 = 11

Therefore, the value for common factors is 11.

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 = 31575503333/(1x11)

LCM = 31575503333/11

LCM = 2870500303

Thus, we can understand that the LCM of 989,913,121,289 is 2870500303.
