Given numbers are 845,85,142

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

The LCM of 845,85,142 is 2039830.

Find LCM of 845,85,142 with Prime Factorization

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

5 x 169 x 17 x 142 = 2039830

Therefore, the lowest common multiple of 845,85,142 is 2039830.

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.

845 x 85 x 142 = 10199150

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.

845 : 1, 5, 13, 65, 169, 845

85 : 1, 5, 17, 85

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,85,142, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

85:5x 17

142:2x 71

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

5 = 5

Therefore, the value for common factors is 5.

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 = 10199150/(1x5)

LCM = 10199150/5

LCM = 2039830

Thus, we can understand that the LCM of 845,85,142 is 2039830.

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

• LCM of 443, 60, 890
• LCM of 781, 77, 811
