Calculate the LCM of 287,566,688,381

Given numbers are 287,566,688,381

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

The LCM of 287,566,688,381 is 21290298288.

Find LCM of 287,566,688,381 with Prime Factorization


2 287, 566, 688, 381
287, 283, 344, 381

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

2 x 287 x 283 x 344 x 381 = 21290298288

Therefore, the lowest common multiple of 287,566,688,381 is 21290298288.

LCM Formula to Find Lowest Common Multiple of 287,566,688,381

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.

287 x 566 x 688 x 381 = 42580596576

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.

287 : 1, 7, 41, 287

566 : 1, 2, 283, 566

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,566,688,381, is 1.

Now, the common factors can be found like this.

287:7x 41

566:2x 283

688:2x 2x 2x 2x 43

381:3x 127

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42580596576/(1x2)

LCM = 42580596576/2

LCM = 21290298288

Thus, we can understand that the LCM of 287,566,688,381 is 21290298288.
