Given numbers are 905,948,989,161

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

The LCM of 905,948,989,161 is 5939518620.

Find LCM of 905,948,989,161 with Prime Factorization

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

23 x 905 x 948 x 43 x 7 = 5939518620

Therefore, the lowest common multiple of 905,948,989,161 is 5939518620.

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.

905 x 948 x 989 x 161 = 136608928260

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.

905 : 1, 5, 181, 905

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

989 : 1, 23, 43, 989

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,948,989,161, is 1.

Now, the common factors can be found like this.

905:5x 181

948:2x 2x 3x 79

989:23x 43

161:7x 23

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

23 = 23

Therefore, the value for common factors is 23.

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 = 136608928260/(1x23)

LCM = 136608928260/23

LCM = 5939518620

Thus, we can understand that the LCM of 905,948,989,161 is 5939518620.

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