Given numbers are 724,181,161,143

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

The LCM of 724,181,161,143 is 16668652.

Find LCM of 724,181,161,143 with Prime Factorization

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

181 x 4 x 1 x 161 x 143 = 16668652

Therefore, the lowest common multiple of 724,181,161,143 is 16668652.

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.

724 x 181 x 161 x 143 = 3017026012

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.

724 : 1, 2, 4, 181, 362, 724

181 : 1, 181

161 : 1, 7, 23, 161

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,181,161,143, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

181:181

161:7x 23

143:11x 13

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

181 = 181

Therefore, the value for common factors is 181.

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 = 3017026012/(1x181)

LCM = 3017026012/181

LCM = 16668652

Thus, we can understand that the LCM of 724,181,161,143 is 16668652.

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

• LCM of 391, 850, 692, 336
