Given numbers are 121,345,161

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

The LCM of 121,345,161 is 292215.

Find LCM of 121,345,161 with Prime Factorization

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

23 x 121 x 15 x 7 = 292215

Therefore, the lowest common multiple of 121,345,161 is 292215.

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.

121 x 345 x 161 = 6720945

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.

121 : 1, 11, 121

345 : 1, 3, 5, 15, 23, 69, 115, 345

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,345,161, is 1.

Now, the common factors can be found like this.

121:11x 11

345:3x 5x 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 = 6720945/(1x23)

LCM = 6720945/23

LCM = 292215

Thus, we can understand that the LCM of 121,345,161 is 292215.

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

• LCM of 403, 537, 189
• LCM of 931, 618, 286
