Calculate the LCM of 286,684,328,380

Given numbers are 286,684,328,380

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

The LCM of 286,684,328,380 is 40102920.

Find LCM of 286,684,328,380 with Prime Factorization


2 286, 684, 328, 380
2 143, 342, 164, 190
19 143, 171, 82, 95
143, 9, 82, 5

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

2 x 2 x 19 x 143 x 9 x 82 x 5 = 40102920

Therefore, the lowest common multiple of 286,684,328,380 is 40102920.

LCM Formula to Find Lowest Common Multiple of 286,684,328,380

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.

286 x 684 x 328 x 380 = 24382575360

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

328 : 1, 2, 4, 8, 41, 82, 164, 328

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,684,328,380, is 2.

Now, the common factors can be found like this.

286:2x 11x 13

684:2x 2x 3x 3x 19

328:2x 2x 2x 41

380:2x 2x 5x 19

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

2x 2x 2x 2x 19 = 304

Therefore, the value for common factors is 304.

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 = 24382575360/(2x304)

LCM = 24382575360/608

LCM = 40102920

Thus, we can understand that the LCM of 286,684,328,380 is 40102920.
