Given numbers are 741,398,489,514,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,398,489,514,278 is 1717262981382.
Find LCM of 741,398,489,514,278 with Prime Factorization
| 2 | 741, 398, 489, 514, 278 |
| 3 | 741, 199, 489, 257, 139 |
| 247, 199, 163, 257, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 247 x 199 x 163 x 257 x 139 = 1717262981382
Therefore, the lowest common multiple of 741,398,489,514,278 is 1717262981382.
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.
741 x 398 x 489 x 514 x 278 = 20607155776584
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
398 : 1, 2, 199, 398
489 : 1, 3, 163, 489
514 : 1, 2, 257, 514
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,398,489,514,278, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
398:2x 199
489:3x 163
514:2x 257
278:2x 139
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 3 = 12
Therefore, the value for common factors is 12.
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 = 20607155776584/(1x12)
LCM = 20607155776584/12
LCM = 1717262981382
Thus, we can understand that the LCM of 741,398,489,514,278 is 1717262981382.
