Given numbers are 149,390,170

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

The LCM of 149,390,170 is 987870.

Find LCM of 149,390,170 with Prime Factorization

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

2 x 5 x 149 x 39 x 17 = 987870

Therefore, the lowest common multiple of 149,390,170 is 987870.

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.

149 x 390 x 170 = 9878700

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.

149 : 1, 149

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

170 : 1, 2, 5, 10, 17, 34, 85, 170

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,390,170, is 1.

Now, the common factors can be found like this.

149:149

390:2x 3x 5x 13

170:2x 5x 17

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 9878700/(1x10)

LCM = 9878700/10

LCM = 987870

Thus, we can understand that the LCM of 149,390,170 is 987870.

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