Given numbers are 393,769,905,237
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 393,769,905,237 is 21607004415.
Find LCM of 393,769,905,237 with Prime Factorization
| 3 | 393, 769, 905, 237 |
| 131, 769, 905, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 131 x 769 x 905 x 79 = 21607004415
Therefore, the lowest common multiple of 393,769,905,237 is 21607004415.
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.
393 x 769 x 905 x 237 = 64821013245
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.
393 : 1, 3, 131, 393
769 : 1, 769
905 : 1, 5, 181, 905
237 : 1, 3, 79, 237
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,769,905,237, is 1.
Now, the common factors can be found like this.
393:3x 131
769:769
905:5x 181
237:3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 64821013245/(1x3)
LCM = 64821013245/3
LCM = 21607004415
Thus, we can understand that the LCM of 393,769,905,237 is 21607004415.
