Given numbers are 351,551,638,771,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,551,638,771,807 is 294148609326.
Find LCM of 351,551,638,771,807 with Prime Factorization
| 3 | 351, 551, 638, 771, 807 |
| 29 | 117, 551, 638, 257, 269 |
| 117, 19, 22, 257, 269 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 117 x 19 x 22 x 257 x 269 = 294148609326
Therefore, the lowest common multiple of 351,551,638,771,807 is 294148609326.
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.
351 x 551 x 638 x 771 x 807 = 76772787034086
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
551 : 1, 19, 29, 551
638 : 1, 2, 11, 22, 29, 58, 319, 638
771 : 1, 3, 257, 771
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,551,638,771,807, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
551:19x 29
638:2x 11x 29
771:3x 257
807:3x 269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 29 = 261
Therefore, the value for common factors is 261.
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 = 76772787034086/(1x261)
LCM = 76772787034086/261
LCM = 294148609326
Thus, we can understand that the LCM of 351,551,638,771,807 is 294148609326.
