Given numbers are 391,820,527
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,820,527 is 9939220.
Find LCM of 391,820,527 with Prime Factorization
| 17 | 391, 820, 527 |
| 23, 820, 31 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 820 x 31 = 9939220
Therefore, the lowest common multiple of 391,820,527 is 9939220.
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.
391 x 820 x 527 = 168966740
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.
391 : 1, 17, 23, 391
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
527 : 1, 17, 31, 527
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,820,527, is 1.
Now, the common factors can be found like this.
391:17x 23
820:2x 2x 5x 41
527:17x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 168966740/(1x17)
LCM = 168966740/17
LCM = 9939220
Thus, we can understand that the LCM of 391,820,527 is 9939220.
