| 3 | 59, 21, 221, 8, 3 |
| 59, 7, 221, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 3 x 59 x 7 x 221 x 8 x 1 = 630878976
Therefore, the lowest common multiple of 118,378,221,768,864 is 630878976.
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.
118 x 378 x 221 x 768 x 864 = 6540953223168
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.
118 : 1, 2, 59, 118
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
221 : 1, 13, 17, 221
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,378,221,768,864, is 1.
Now, the common factors can be found like this.
118:2x 59
378:2x 3x 3x 3x 7
221:13x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
864:2x 2x 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 2x 2x 2x 2x 2x 3x 3x 3x 3 = 10368
Therefore, the value for common factors is 10368.
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 = 6540953223168/(1x10368)
LCM = 6540953223168/10368
LCM = 630878976
Thus, we can understand that the LCM of 118,378,221,768,864 is 630878976.
