Given numbers are 199,77,990

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

The LCM of 199,77,990 is 1379070.

Find LCM of 199,77,990 with Prime Factorization

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

11 x 199 x 7 x 90 = 1379070

Therefore, the lowest common multiple of 199,77,990 is 1379070.

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.

199 x 77 x 990 = 15169770

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.

199 : 1, 199

77 : 1, 7, 11, 77

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 199,77,990, is 1.

Now, the common factors can be found like this.

199:199

77:7x 11

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 = 15169770/(1x11)

LCM = 15169770/11

LCM = 1379070

Thus, we can understand that the LCM of 199,77,990 is 1379070.

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

• LCM of 205, 29, 324
