Given numbers are 642,327,327,666,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,327,327,666,551 is 4279924458.
Find LCM of 642,327,327,666,551 with Prime Factorization
| 2 | 642, 327, 327, 666, 551 |
| 3 | 321, 327, 327, 333, 551 |
| 109 | 107, 109, 109, 111, 551 |
| 107, 1, 1, 111, 551 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 107 x 1 x 1 x 111 x 551 = 4279924458
Therefore, the lowest common multiple of 642,327,327,666,551 is 4279924458.
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.
642 x 327 x 327 x 666 x 551 = 25191635359788
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
327 : 1, 3, 109, 327
327 : 1, 3, 109, 327
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,327,327,666,551, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
327:3x 109
327:3x 109
666:2x 3x 3x 37
551:19x 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 3x 3x 3x 109 = 5886
Therefore, the value for common factors is 5886.
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 = 25191635359788/(1x5886)
LCM = 25191635359788/5886
LCM = 4279924458
Thus, we can understand that the LCM of 642,327,327,666,551 is 4279924458.
