Given numbers are 626,445,172,208,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,445,172,208,285 is 71008607280.
Find LCM of 626,445,172,208,285 with Prime Factorization
| 2 | 626, 445, 172, 208, 285 |
| 2 | 313, 445, 86, 104, 285 |
| 5 | 313, 445, 43, 52, 285 |
| 313, 89, 43, 52, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 313 x 89 x 43 x 52 x 57 = 71008607280
Therefore, the lowest common multiple of 626,445,172,208,285 is 71008607280.
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.
626 x 445 x 172 x 208 x 285 = 2840344291200
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.
626 : 1, 2, 313, 626
445 : 1, 5, 89, 445
172 : 1, 2, 4, 43, 86, 172
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,445,172,208,285, is 1.
Now, the common factors can be found like this.
626:2x 313
445:5x 89
172:2x 2x 43
208:2x 2x 2x 2x 13
285:3x 5x 19
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 2840344291200/(1x40)
LCM = 2840344291200/40
LCM = 71008607280
Thus, we can understand that the LCM of 626,445,172,208,285 is 71008607280.
