Given numbers are 578,986,836,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,986,836,667 is 161149868.
Find LCM of 578,986,836,667 with Prime Factorization
| 2 | 578, 986, 836, 667 |
| 17 | 289, 493, 418, 667 |
| 29 | 17, 29, 418, 667 |
| 17, 1, 418, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 29 x 17 x 1 x 418 x 23 = 161149868
Therefore, the lowest common multiple of 578,986,836,667 is 161149868.
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.
578 x 986 x 836 x 667 = 317787539696
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.
578 : 1, 2, 17, 34, 289, 578
986 : 1, 2, 17, 29, 34, 58, 493, 986
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,986,836,667, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
986:2x 17x 29
836:2x 2x 11x 19
667:23x 29
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 17x 29 = 1972
Therefore, the value for common factors is 1972.
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 = 317787539696/(1x1972)
LCM = 317787539696/1972
LCM = 161149868
Thus, we can understand that the LCM of 578,986,836,667 is 161149868.
