Find LCM of 994,418,816,978,242 with Prime Factorization
2 | 994, 418, 816, 978, 242 |
3 | 497, 209, 408, 489, 121 |
11 | 497, 209, 136, 163, 121 |
497, 19, 136, 163, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 497 x 19 x 136 x 163 x 11 = 151975339824
Therefore, the lowest common multiple of 994,418,816,978,242 is 151975339824.
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.
994 x 418 x 816 x 978 x 242 = 80242979427072
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
418 : 1, 2, 11, 19, 22, 38, 209, 418
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
978 : 1, 2, 3, 6, 163, 326, 489, 978
242 : 1, 2, 11, 22, 121, 242
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,418,816,978,242, is 2.
Now, the common factors can be found like this.
994:2x 7x 71
418:2x 11x 19
816:2x 2x 2x 2x 3x 17
978:2x 3x 163
242:2x 11x 11
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 80242979427072/(2x264)
LCM = 80242979427072/528
LCM = 151975339824
Thus, we can understand that the LCM of 994,418,816,978,242 is 151975339824.
