Given numbers are 42,93,45,93,491

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

The LCM of 42,93,45,93,491 is 9589230.

Find LCM of 42,93,45,93,491 with Prime Factorization

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

3 x 31 x 14 x 1 x 15 x 1 x 491 = 9589230

Therefore, the lowest common multiple of 42,93,45,93,491 is 9589230.

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.

42 x 93 x 45 x 93 x 491 = 8026185510

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.

42 : 1, 2, 3, 6, 7, 14, 21, 42

93 : 1, 3, 31, 93

45 : 1, 3, 5, 9, 15, 45

93 : 1, 3, 31, 93

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 42,93,45,93,491, is 1.

Now, the common factors can be found like this.

42:2x 3x 7

93:3x 31

45:3x 3x 5

93:3x 31

491:491

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

3x 3x 3x 31 = 837

Therefore, the value for common factors is 837.

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 = 8026185510/(1x837)

LCM = 8026185510/837

LCM = 9589230

Thus, we can understand that the LCM of 42,93,45,93,491 is 9589230.
