Given numbers are 989,138,161

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

The LCM of 989,138,161 is 41538.

Find LCM of 989,138,161 with Prime Factorization

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

23 x 43 x 6 x 7 = 41538

Therefore, the lowest common multiple of 989,138,161 is 41538.

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 138 x 161 = 21973602

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

161 : 1, 7, 23, 161

23 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,138,161, is 23.

Now, the common factors can be found like this.

989:23x 43

138:2x 3x 23

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 = 21973602/(23x23)

LCM = 21973602/529

LCM = 41538

Thus, we can understand that the LCM of 989,138,161 is 41538.

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

• LCM of 903, 962, 924
• LCM of 756, 827, 483
