Given numbers are 398,607,212,821,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,607,212,821,122 is 1282480057396.
Find LCM of 398,607,212,821,122 with Prime Factorization
| 2 | 398, 607, 212, 821, 122 |
| 199, 607, 106, 821, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 607 x 106 x 821 x 61 = 1282480057396
Therefore, the lowest common multiple of 398,607,212,821,122 is 1282480057396.
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.
398 x 607 x 212 x 821 x 122 = 5129920229584
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.
398 : 1, 2, 199, 398
607 : 1, 607
212 : 1, 2, 4, 53, 106, 212
821 : 1, 821
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,607,212,821,122, is 1.
Now, the common factors can be found like this.
398:2x 199
607:607
212:2x 2x 53
821:821
122:2x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 5129920229584/(1x4)
LCM = 5129920229584/4
LCM = 1282480057396
Thus, we can understand that the LCM of 398,607,212,821,122 is 1282480057396.
