Calculate the LCM of 891,362,145,385

Given numbers are 891,362,145,385

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

The LCM of 891,362,145,385 is 327380130.

Find LCM of 891,362,145,385 with Prime Factorization


5 891, 362, 145, 385
11 891, 362, 29, 77
81, 362, 29, 7

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

5 x 11 x 81 x 362 x 29 x 7 = 327380130

Therefore, the lowest common multiple of 891,362,145,385 is 327380130.

LCM Formula to Find Lowest Common Multiple of 891,362,145,385

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.

891 x 362 x 145 x 385 = 18005907150

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

362 : 1, 2, 181, 362

145 : 1, 5, 29, 145

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,362,145,385, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

362:2x 181

145:5x 29

385:5x 7x 11

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

5x 11 = 55

Therefore, the value for common factors is 55.

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 = 18005907150/(1x55)

LCM = 18005907150/55

LCM = 327380130

Thus, we can understand that the LCM of 891,362,145,385 is 327380130.
