Given numbers are 898,169,198,138

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

The LCM of 898,169,198,138 is 345562074.

Find LCM of 898,169,198,138 with Prime Factorization

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

2 x 3 x 449 x 169 x 33 x 23 = 345562074

Therefore, the lowest common multiple of 898,169,198,138 is 345562074.

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.

898 x 169 x 198 x 138 = 4146744888

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.

898 : 1, 2, 449, 898

169 : 1, 13, 169

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,169,198,138, is 1.

Now, the common factors can be found like this.

898:2x 449

169:13x 13

198:2x 3x 3x 11

138:2x 3x 23

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 4146744888/(1x12)

LCM = 4146744888/12

LCM = 345562074

Thus, we can understand that the LCM of 898,169,198,138 is 345562074.

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