Calculate the LCM of 388,786,886,238

Given numbers are 388,786,886,238

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

The LCM of 388,786,886,238 is 8038499028.

Find LCM of 388,786,886,238 with Prime Factorization


2 388, 786, 886, 238
194, 393, 443, 119

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

2 x 194 x 393 x 443 x 119 = 8038499028

Therefore, the lowest common multiple of 388,786,886,238 is 8038499028.

LCM Formula to Find Lowest Common Multiple of 388,786,886,238

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.

388 x 786 x 886 x 238 = 64307992224

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.

388 : 1, 2, 4, 97, 194, 388

786 : 1, 2, 3, 6, 131, 262, 393, 786

886 : 1, 2, 443, 886

238 : 1, 2, 7, 14, 17, 34, 119, 238

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,786,886,238, is 2.

Now, the common factors can be found like this.

388:2x 2x 97

786:2x 3x 131

886:2x 443

238:2x 7x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 64307992224/(2x4)

LCM = 64307992224/8

LCM = 8038499028

Thus, we can understand that the LCM of 388,786,886,238 is 8038499028.
