Given numbers are 363,817,946,987,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,817,946,987,391 is 76301193738.
Find LCM of 363,817,946,987,391 with Prime Factorization
| 3 | 363, 817, 946, 987, 391 |
| 11 | 121, 817, 946, 329, 391 |
| 43 | 11, 817, 86, 329, 391 |
| 11, 19, 2, 329, 391 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 43 x 11 x 19 x 2 x 329 x 391 = 76301193738
Therefore, the lowest common multiple of 363,817,946,987,391 is 76301193738.
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.
363 x 817 x 946 x 987 x 391 = 108271393914222
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.
363 : 1, 3, 11, 33, 121, 363
817 : 1, 19, 43, 817
946 : 1, 2, 11, 22, 43, 86, 473, 946
987 : 1, 3, 7, 21, 47, 141, 329, 987
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,817,946,987,391, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
817:19x 43
946:2x 11x 43
987:3x 7x 47
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 43 = 1419
Therefore, the value for common factors is 1419.
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 = 108271393914222/(1x1419)
LCM = 108271393914222/1419
LCM = 76301193738
Thus, we can understand that the LCM of 363,817,946,987,391 is 76301193738.
