Given numbers are 163,138,889,990

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

The LCM of 163,138,889,990 is 3299532390.

Find LCM of 163,138,889,990 with Prime Factorization

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

2 x 3 x 163 x 23 x 889 x 165 = 3299532390

Therefore, the lowest common multiple of 163,138,889,990 is 3299532390.

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.

163 x 138 x 889 x 990 = 19797194340

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.

163 : 1, 163

138 : 1, 2, 3, 6, 23, 46, 69, 138

889 : 1, 7, 127, 889

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 163,138,889,990, is 1.

Now, the common factors can be found like this.

163:163

138:2x 3x 23

889:7x 127

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 19797194340/(1x6)

LCM = 19797194340/6

LCM = 3299532390

Thus, we can understand that the LCM of 163,138,889,990 is 3299532390.
