Given numbers are 249,398,663,521,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,398,663,521,217 is 2476122633894.
Find LCM of 249,398,663,521,217 with Prime Factorization
| 3 | 249, 398, 663, 521, 217 |
| 83, 398, 221, 521, 217 |
Multiply the prime numbers at the bottom and the left side.
3 x 83 x 398 x 221 x 521 x 217 = 2476122633894
Therefore, the lowest common multiple of 249,398,663,521,217 is 2476122633894.
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.
249 x 398 x 663 x 521 x 217 = 7428367901682
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.
249 : 1, 3, 83, 249
398 : 1, 2, 199, 398
663 : 1, 3, 13, 17, 39, 51, 221, 663
521 : 1, 521
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,398,663,521,217, is 1.
Now, the common factors can be found like this.
249:3x 83
398:2x 199
663:3x 13x 17
521:521
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 7428367901682/(1x3)
LCM = 7428367901682/3
LCM = 2476122633894
Thus, we can understand that the LCM of 249,398,663,521,217 is 2476122633894.
