Given numbers are 398,759,309,774
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,759,309,774 is 4013763534.
Find LCM of 398,759,309,774 with Prime Factorization
| 2 | 398, 759, 309, 774 |
| 3 | 199, 759, 309, 387 |
| 199, 253, 103, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 199 x 253 x 103 x 129 = 4013763534
Therefore, the lowest common multiple of 398,759,309,774 is 4013763534.
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.
398 x 759 x 309 x 774 = 72247743612
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.
398 : 1, 2, 199, 398
759 : 1, 3, 11, 23, 33, 69, 253, 759
309 : 1, 3, 103, 309
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,759,309,774, is 1.
Now, the common factors can be found like this.
398:2x 199
759:3x 11x 23
309:3x 103
774:2x 3x 3x 43
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 3 = 18
Therefore, the value for common factors is 18.
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 = 72247743612/(1x18)
LCM = 72247743612/18
LCM = 4013763534
Thus, we can understand that the LCM of 398,759,309,774 is 4013763534.
