Given numbers are 387,747,669,901,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,747,669,901,107 is 690561702081.
Find LCM of 387,747,669,901,107 with Prime Factorization
| 3 | 387, 747, 669, 901, 107 |
| 3 | 129, 249, 223, 901, 107 |
| 43, 83, 223, 901, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 83 x 223 x 901 x 107 = 690561702081
Therefore, the lowest common multiple of 387,747,669,901,107 is 690561702081.
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.
387 x 747 x 669 x 901 x 107 = 18645165956187
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.
387 : 1, 3, 9, 43, 129, 387
747 : 1, 3, 9, 83, 249, 747
669 : 1, 3, 223, 669
901 : 1, 17, 53, 901
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,747,669,901,107, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
747:3x 3x 83
669:3x 223
901:17x 53
107:107
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 3 = 27
Therefore, the value for common factors is 27.
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 = 18645165956187/(1x27)
LCM = 18645165956187/27
LCM = 690561702081
Thus, we can understand that the LCM of 387,747,669,901,107 is 690561702081.
