Given numbers are 911,990,121,923

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

The LCM of 911,990,121,923 is 9156889170.

Find LCM of 911,990,121,923 with Prime Factorization

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

11 x 911 x 90 x 11 x 923 = 9156889170

Therefore, the lowest common multiple of 911,990,121,923 is 9156889170.

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.

911 x 990 x 121 x 923 = 100725780870

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.

911 : 1, 911

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

121 : 1, 11, 121

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,990,121,923, is 1.

Now, the common factors can be found like this.

911:911

990:2x 3x 3x 5x 11

121:11x 11

923:13x 71

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 = 100725780870/(1x11)

LCM = 100725780870/11

LCM = 9156889170

Thus, we can understand that the LCM of 911,990,121,923 is 9156889170.

Here are some samples of LCM of two or more Numbers calculations.
