Given numbers are 3771,1539

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

The LCM of 3771,1539 is 644841.

Find LCM of 3771,1539 with Prime Factorization

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

3 x 3 x 419 x 171 = 644841

Therefore, the lowest common multiple of 3771,1539 is 644841.

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.

3771 x 1539 = 5803569

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.

3771 : 1, 3, 9, 419, 1257, 3771

1539 : 1, 3, 9, 19, 27, 57, 81, 171, 513, 1539

9 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3771,1539, is 9.

Now, the common factors can be found like this.

3771:3x 3x 419

1539:3x 3x 3x 3x 19

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 = 5803569/(9x1)

LCM = 5803569/9

LCM = 644841

Thus, we can understand that the LCM of 3771,1539 is 644841.
