Given numbers are 749,187,990

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

The LCM of 749,187,990 is 12605670.

Find LCM of 749,187,990 with Prime Factorization

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

11 x 749 x 17 x 90 = 12605670

Therefore, the lowest common multiple of 749,187,990 is 12605670.

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.

749 x 187 x 990 = 138662370

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.

749 : 1, 7, 107, 749

187 : 1, 11, 17, 187

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,187,990, is 1.

Now, the common factors can be found like this.

749:7x 107

187:11x 17

990:2x 3x 3x 5x 11

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

11 = 11

Therefore, the value for common factors is 11.

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 = 138662370/(1x11)

LCM = 138662370/11

LCM = 12605670

Thus, we can understand that the LCM of 749,187,990 is 12605670.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 691, 604, 428
