Given numbers are 417,560,965,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,560,965,392 is 315485520.
Find LCM of 417,560,965,392 with Prime Factorization
| 2 | 417, 560, 965, 392 |
| 2 | 417, 280, 965, 196 |
| 2 | 417, 140, 965, 98 |
| 5 | 417, 70, 965, 49 |
| 7 | 417, 14, 193, 49 |
| 417, 2, 193, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 417 x 2 x 193 x 7 = 315485520
Therefore, the lowest common multiple of 417,560,965,392 is 315485520.
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.
417 x 560 x 965 x 392 = 88335945600
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.
417 : 1, 3, 139, 417
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
965 : 1, 5, 193, 965
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,560,965,392, is 1.
Now, the common factors can be found like this.
417:3x 139
560:2x 2x 2x 2x 5x 7
965:5x 193
392:2x 2x 2x 7x 7
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 88335945600/(1x280)
LCM = 88335945600/280
LCM = 315485520
Thus, we can understand that the LCM of 417,560,965,392 is 315485520.
