Given numbers are 127,315,518,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,315,518,645 is 127295910.
Find LCM of 127,315,518,645 with Prime Factorization
| 3 | 127, 315, 518, 645 |
| 5 | 127, 105, 518, 215 |
| 7 | 127, 21, 518, 43 |
| 127, 3, 74, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 127 x 3 x 74 x 43 = 127295910
Therefore, the lowest common multiple of 127,315,518,645 is 127295910.
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.
127 x 315 x 518 x 645 = 13366070550
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.
127 : 1, 127
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
518 : 1, 2, 7, 14, 37, 74, 259, 518
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,315,518,645, is 1.
Now, the common factors can be found like this.
127:127
315:3x 3x 5x 7
518:2x 7x 37
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7 = 105
Therefore, the value for common factors is 105.
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 = 13366070550/(1x105)
LCM = 13366070550/105
LCM = 127295910
Thus, we can understand that the LCM of 127,315,518,645 is 127295910.
