Given numbers are 853,403,172,258

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

The LCM of 853,403,172,258 is 177379644.

Find LCM of 853,403,172,258 with Prime Factorization

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

2 x 43 x 853 x 403 x 2 x 3 = 177379644

Therefore, the lowest common multiple of 853,403,172,258 is 177379644.

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.

853 x 403 x 172 x 258 = 15254649384

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.

853 : 1, 853

403 : 1, 13, 31, 403

172 : 1, 2, 4, 43, 86, 172

258 : 1, 2, 3, 6, 43, 86, 129, 258

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,403,172,258, is 1.

Now, the common factors can be found like this.

853:853

403:13x 31

172:2x 2x 43

258:2x 3x 43

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

2x 43 = 86

Therefore, the value for common factors is 86.

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 = 15254649384/(1x86)

LCM = 15254649384/86

LCM = 177379644

Thus, we can understand that the LCM of 853,403,172,258 is 177379644.
