Given numbers are 923,1690

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

The LCM of 923,1690 is 119990.

Find LCM of 923,1690 with Prime Factorization

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

13 x 71 x 130 = 119990

Therefore, the lowest common multiple of 923,1690 is 119990.

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.

923 x 1690 = 1559870

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.

923 : 1, 13, 71, 923

1690 : 1, 2, 5, 10, 13, 26, 65, 130, 169, 338, 845, 1690

13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,1690, is 13.

Now, the common factors can be found like this.

923:13x 71

1690:2x 5x 13x 13

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

= 1

Therefore, the value for common factors is 1.

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 = 1559870/(13x1)

LCM = 1559870/13

LCM = 119990

Thus, we can understand that the LCM of 923,1690 is 119990.
