Given numbers are 645,310,618,795,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,310,618,795,279 is 654916230.
Find LCM of 645,310,618,795,279 with Prime Factorization
| 2 | 645, 310, 618, 795, 279 |
| 3 | 645, 155, 309, 795, 279 |
| 5 | 215, 155, 103, 265, 93 |
| 31 | 43, 31, 103, 53, 93 |
| 43, 1, 103, 53, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 43 x 1 x 103 x 53 x 3 = 654916230
Therefore, the lowest common multiple of 645,310,618,795,279 is 654916230.
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.
645 x 310 x 618 x 795 x 279 = 27408244225500
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
310 : 1, 2, 5, 10, 31, 62, 155, 310
618 : 1, 2, 3, 6, 103, 206, 309, 618
795 : 1, 3, 5, 15, 53, 159, 265, 795
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,310,618,795,279, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
310:2x 5x 31
618:2x 3x 103
795:3x 5x 53
279:3x 3x 31
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 3x 3x 5x 5x 31 = 41850
Therefore, the value for common factors is 41850.
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 = 27408244225500/(1x41850)
LCM = 27408244225500/41850
LCM = 654916230
Thus, we can understand that the LCM of 645,310,618,795,279 is 654916230.
