Calculate the LCM of 390,122,877,305

Given numbers are 390,122,877,305

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

The LCM of 390,122,877,305 is 20863830.

Find LCM of 390,122,877,305 with Prime Factorization


2 390, 122, 877, 305
5 195, 61, 877, 305
61 39, 61, 877, 61
39, 1, 877, 1

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

2 x 5 x 61 x 39 x 1 x 877 x 1 = 20863830

Therefore, the lowest common multiple of 390,122,877,305 is 20863830.

LCM Formula to Find Lowest Common Multiple of 390,122,877,305

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.

390 x 122 x 877 x 305 = 12726936300

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.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

122 : 1, 2, 61, 122

877 : 1, 877

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,122,877,305, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

122:2x 61

877:877

305:5x 61

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

2x 5x 61 = 610

Therefore, the value for common factors is 610.

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 = 12726936300/(1x610)

LCM = 12726936300/610

LCM = 20863830

Thus, we can understand that the LCM of 390,122,877,305 is 20863830.
