Given numbers are 647,817,228,647,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,817,228,647,409 is 2594363892.
Find LCM of 647,817,228,647,409 with Prime Factorization
| 19 | 647, 817, 228, 647, 409 |
| 647 | 647, 43, 12, 647, 409 |
| 1, 43, 12, 1, 409 |
Multiply the prime numbers at the bottom and the left side.
19 x 647 x 1 x 43 x 12 x 1 x 409 = 2594363892
Therefore, the lowest common multiple of 647,817,228,647,409 is 2594363892.
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 817 x 228 x 647 x 409 = 31892515324356
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
817 : 1, 19, 43, 817
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
647 : 1, 647
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,817,228,647,409, is 1.
Now, the common factors can be found like this.
647:647
817:19x 43
228:2x 2x 3x 19
647:647
409:409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19x 647 = 12293
Therefore, the value for common factors is 12293.
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 = 31892515324356/(1x12293)
LCM = 31892515324356/12293
LCM = 2594363892
Thus, we can understand that the LCM of 647,817,228,647,409 is 2594363892.
