Given numbers are 119,128,990

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

The LCM of 119,128,990 is 7539840.

Find LCM of 119,128,990 with Prime Factorization

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

2 x 119 x 64 x 495 = 7539840

Therefore, the lowest common multiple of 119,128,990 is 7539840.

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.

119 x 128 x 990 = 15079680

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.

119 : 1, 7, 17, 119

128 : 1, 2, 4, 8, 16, 32, 64, 128

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 119,128,990, is 1.

Now, the common factors can be found like this.

119:7x 17

128:2x 2x 2x 2x 2x 2x 2

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 15079680/(1x2)

LCM = 15079680/2

LCM = 7539840

Thus, we can understand that the LCM of 119,128,990 is 7539840.

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

• LCM of 890, 792, 183
