Given numbers are 272,308,987,611,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,308,987,611,505 is 19387127760.
Find LCM of 272,308,987,611,505 with Prime Factorization
| 2 | 272, 308, 987, 611, 505 |
| 2 | 136, 154, 987, 611, 505 |
| 7 | 68, 77, 987, 611, 505 |
| 47 | 68, 11, 141, 611, 505 |
| 68, 11, 3, 13, 505 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 47 x 68 x 11 x 3 x 13 x 505 = 19387127760
Therefore, the lowest common multiple of 272,308,987,611,505 is 19387127760.
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.
272 x 308 x 987 x 611 x 505 = 25513460132160
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
987 : 1, 3, 7, 21, 47, 141, 329, 987
611 : 1, 13, 47, 611
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,308,987,611,505, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
308:2x 2x 7x 11
987:3x 7x 47
611:13x 47
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 2x 7x 47 = 1316
Therefore, the value for common factors is 1316.
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 = 25513460132160/(1x1316)
LCM = 25513460132160/1316
LCM = 19387127760
Thus, we can understand that the LCM of 272,308,987,611,505 is 19387127760.
