Given numbers are 667,817,418,991,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,817,418,991,772 is 4585973390108.
Find LCM of 667,817,418,991,772 with Prime Factorization
| 2 | 667, 817, 418, 991, 772 |
| 19 | 667, 817, 209, 991, 386 |
| 667, 43, 11, 991, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 667 x 43 x 11 x 991 x 386 = 4585973390108
Therefore, the lowest common multiple of 667,817,418,991,772 is 4585973390108.
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.
667 x 817 x 418 x 991 x 772 = 174266988824104
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.
667 : 1, 23, 29, 667
817 : 1, 19, 43, 817
418 : 1, 2, 11, 19, 22, 38, 209, 418
991 : 1, 991
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,817,418,991,772, is 1.
Now, the common factors can be found like this.
667:23x 29
817:19x 43
418:2x 11x 19
991:991
772:2x 2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 174266988824104/(1x38)
LCM = 174266988824104/38
LCM = 4585973390108
Thus, we can understand that the LCM of 667,817,418,991,772 is 4585973390108.
