Given numbers are 551,919,982,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,919,982,638 is 5469797938.
Find LCM of 551,919,982,638 with Prime Factorization
| 2 | 551, 919, 982, 638 |
| 29 | 551, 919, 491, 319 |
| 19, 919, 491, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 19 x 919 x 491 x 11 = 5469797938
Therefore, the lowest common multiple of 551,919,982,638 is 5469797938.
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.
551 x 919 x 982 x 638 = 317248280404
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.
551 : 1, 19, 29, 551
919 : 1, 919
982 : 1, 2, 491, 982
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,919,982,638, is 1.
Now, the common factors can be found like this.
551:19x 29
919:919
982:2x 491
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29 = 58
Therefore, the value for common factors is 58.
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 = 317248280404/(1x58)
LCM = 317248280404/58
LCM = 5469797938
Thus, we can understand that the LCM of 551,919,982,638 is 5469797938.
