Calculate the LCM of 684,289,322,766,643

Given numbers are 684,289,322,766,643

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

The LCM of 684,289,322,766,643 is 7837716805884.

Find LCM of 684,289,322,766,643 with Prime Factorization


2 684, 289, 322, 766, 643
342, 289, 161, 383, 643

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

2 x 342 x 289 x 161 x 383 x 643 = 7837716805884

Therefore, the lowest common multiple of 684,289,322,766,643 is 7837716805884.

LCM Formula to Find Lowest Common Multiple of 684,289,322,766,643

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.

684 x 289 x 322 x 766 x 643 = 31350867223536

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.

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

289 : 1, 17, 289

322 : 1, 2, 7, 14, 23, 46, 161, 322

766 : 1, 2, 383, 766

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,289,322,766,643, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

289:17x 17

322:2x 7x 23

766:2x 383

643:643

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 = 31350867223536/(1x4)

LCM = 31350867223536/4

LCM = 7837716805884

Thus, we can understand that the LCM of 684,289,322,766,643 is 7837716805884.
