Given numbers are 471,421,261,442,272
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,421,261,442,272 is 61000656912.
Find LCM of 471,421,261,442,272 with Prime Factorization
| 2 | 471, 421, 261, 442, 272 |
| 3 | 471, 421, 261, 221, 136 |
| 17 | 157, 421, 87, 221, 136 |
| 157, 421, 87, 13, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 157 x 421 x 87 x 13 x 8 = 61000656912
Therefore, the lowest common multiple of 471,421,261,442,272 is 61000656912.
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.
471 x 421 x 261 x 442 x 272 = 6222067005024
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.
471 : 1, 3, 157, 471
421 : 1, 421
261 : 1, 3, 9, 29, 87, 261
442 : 1, 2, 13, 17, 26, 34, 221, 442
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,421,261,442,272, is 1.
Now, the common factors can be found like this.
471:3x 157
421:421
261:3x 3x 29
442:2x 13x 17
272:2x 2x 2x 2x 17
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 17 = 102
Therefore, the value for common factors is 102.
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 = 6222067005024/(1x102)
LCM = 6222067005024/102
LCM = 61000656912
Thus, we can understand that the LCM of 471,421,261,442,272 is 61000656912.
