Calculate the LCM of 149,845,842,945

Given numbers are 149,845,842,945

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

The LCM of 149,845,842,945 is 20036269890.

Find LCM of 149,845,842,945 with Prime Factorization


5 149, 845, 842, 945
149, 169, 842, 189

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

5 x 149 x 169 x 842 x 189 = 20036269890

Therefore, the lowest common multiple of 149,845,842,945 is 20036269890.

LCM Formula to Find Lowest Common Multiple of 149,845,842,945

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.

149 x 845 x 842 x 945 = 100181349450

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.

149 : 1, 149

845 : 1, 5, 13, 65, 169, 845

842 : 1, 2, 421, 842

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 149,845,842,945, is 1.

Now, the common factors can be found like this.

149:149

845:5x 13x 13

842:2x 421

945:3x 3x 3x 5x 7

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

5 = 5

Therefore, the value for common factors is 5.

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 = 100181349450/(1x5)

LCM = 100181349450/5

LCM = 20036269890

Thus, we can understand that the LCM of 149,845,842,945 is 20036269890.
