Given numbers are 813,169,139,923

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

The LCM of 813,169,139,923 is 1355970993.

Find LCM of 813,169,139,923 with Prime Factorization

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

13 x 813 x 13 x 139 x 71 = 1355970993

Therefore, the lowest common multiple of 813,169,139,923 is 1355970993.

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.

813 x 169 x 139 x 923 = 17627622909

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.

813 : 1, 3, 271, 813

169 : 1, 13, 169

139 : 1, 139

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,169,139,923, is 1.

Now, the common factors can be found like this.

813:3x 271

169:13x 13

139:139

923:13x 71

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

13 = 13

Therefore, the value for common factors is 13.

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 = 17627622909/(1x13)

LCM = 17627622909/13

LCM = 1355970993

Thus, we can understand that the LCM of 813,169,139,923 is 1355970993.
