Given numbers are 705,218,968,969,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,218,968,969,505 is 2426693173080.
Find LCM of 705,218,968,969,505 with Prime Factorization
| 2 | 705, 218, 968, 969, 505 |
| 3 | 705, 109, 484, 969, 505 |
| 5 | 235, 109, 484, 323, 505 |
| 47, 109, 484, 323, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 109 x 484 x 323 x 101 = 2426693173080
Therefore, the lowest common multiple of 705,218,968,969,505 is 2426693173080.
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.
705 x 218 x 968 x 969 x 505 = 72800795192400
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
218 : 1, 2, 109, 218
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
969 : 1, 3, 17, 19, 51, 57, 323, 969
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,218,968,969,505, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
218:2x 109
968:2x 2x 2x 11x 11
969:3x 17x 19
505:5x 101
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 5 = 30
Therefore, the value for common factors is 30.
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 = 72800795192400/(1x30)
LCM = 72800795192400/30
LCM = 2426693173080
Thus, we can understand that the LCM of 705,218,968,969,505 is 2426693173080.
