The LCM of 986,418,374,216 is 22255992.
Find LCM of 986,418,374,216 with Prime Factorization
| 2 | 986, 418, 374, 216 |
| 11 | 493, 209, 187, 108 |
| 17 | 493, 19, 17, 108 |
| 29, 19, 1, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 29 x 19 x 1 x 108 = 22255992
Therefore, the lowest common multiple of 986,418,374,216 is 22255992.
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.
986 x 418 x 374 x 216 = 33294964032
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
418 : 1, 2, 11, 19, 22, 38, 209, 418
374 : 1, 2, 11, 17, 22, 34, 187, 374
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,418,374,216, is 2.
Now, the common factors can be found like this.
986:2x 17x 29
418:2x 11x 19
374:2x 11x 17
216:2x 2x 2x 3x 3x 3
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 33294964032/(2x748)
LCM = 33294964032/1496
LCM = 22255992
Thus, we can understand that the LCM of 986,418,374,216 is 22255992.
