Given numbers are 340,614,392,399,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,614,392,399,968 is 70551068280.
Find LCM of 340,614,392,399,968 with Prime Factorization
| 2 | 340, 614, 392, 399, 968 |
| 2 | 170, 307, 196, 399, 484 |
| 2 | 85, 307, 98, 399, 242 |
| 7 | 85, 307, 49, 399, 121 |
| 85, 307, 7, 57, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 85 x 307 x 7 x 57 x 121 = 70551068280
Therefore, the lowest common multiple of 340,614,392,399,968 is 70551068280.
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.
340 x 614 x 392 x 399 x 968 = 31606878589440
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
614 : 1, 2, 307, 614
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
399 : 1, 3, 7, 19, 21, 57, 133, 399
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,614,392,399,968, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
614:2x 307
392:2x 2x 2x 7x 7
399:3x 7x 19
968:2x 2x 2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 7 = 448
Therefore, the value for common factors is 448.
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 = 31606878589440/(1x448)
LCM = 31606878589440/448
LCM = 70551068280
Thus, we can understand that the LCM of 340,614,392,399,968 is 70551068280.
