Given numbers are 1445,1921

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

The LCM of 1445,1921 is 163285.

Find LCM of 1445,1921 with Prime Factorization

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

17 x 85 x 113 = 163285

Therefore, the lowest common multiple of 1445,1921 is 163285.

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.

1445 x 1921 = 2775845

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.

1445 : 1, 5, 17, 85, 289, 1445

1921 : 1, 17, 113, 1921

17 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1445,1921, is 17.

Now, the common factors can be found like this.

1445:5x 17x 17

1921:17x 113

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 = 2775845/(17x1)

LCM = 2775845/17

LCM = 163285

Thus, we can understand that the LCM of 1445,1921 is 163285.
