Given numbers are 234,487,986,420,805

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

The LCM of 234,487,986,420,805 is 90451883340.

Find LCM of 234,487,986,420,805 with Prime Factorization

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

2 x 3 x 5 x 7 x 39 x 487 x 493 x 2 x 23 = 90451883340

Therefore, the lowest common multiple of 234,487,986,420,805 is 90451883340.

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.

234 x 487 x 986 x 420 x 805 = 37989791002800

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.

234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234

487 : 1, 487

986 : 1, 2, 17, 29, 34, 58, 493, 986

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 234,487,986,420,805, is 1.

Now, the common factors can be found like this.

234:2x 3x 3x 13

487:487

986:2x 17x 29

420:2x 2x 3x 5x 7

805:5x 7x 23

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 3x 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 37989791002800/(1x420)

LCM = 37989791002800/420

LCM = 90451883340

Thus, we can understand that the LCM of 234,487,986,420,805 is 90451883340.
