Given numbers are 647,293,115,805,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,293,115,805,422 is 64399164410.
Find LCM of 647,293,115,805,422 with Prime Factorization
| 5 | 647, 293, 115, 805, 422 |
| 23 | 647, 293, 23, 161, 422 |
| 647, 293, 1, 7, 422 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 647 x 293 x 1 x 7 x 422 = 64399164410
Therefore, the lowest common multiple of 647,293,115,805,422 is 64399164410.
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.
647 x 293 x 115 x 805 x 422 = 7405903907150
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.
647 : 1, 647
293 : 1, 293
115 : 1, 5, 23, 115
805 : 1, 5, 7, 23, 35, 115, 161, 805
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,293,115,805,422, is 1.
Now, the common factors can be found like this.
647:647
293:293
115:5x 23
805:5x 7x 23
422:2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23 = 115
Therefore, the value for common factors is 115.
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 = 7405903907150/(1x115)
LCM = 7405903907150/115
LCM = 64399164410
Thus, we can understand that the LCM of 647,293,115,805,422 is 64399164410.
