Find LCM of 117,788,861,990,224 with Prime Factorization
| 2 | 117, 788, 861, 990, 224 |
| 2 | 117, 394, 861, 495, 112 |
| 3 | 117, 197, 861, 495, 56 |
| 3 | 39, 197, 287, 165, 56 |
| 7 | 13, 197, 287, 55, 56 |
| 13, 197, 41, 55, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 13 x 197 x 41 x 55 x 8 = 11642510880
Therefore, the lowest common multiple of 117,788,861,990,224 is 11642510880.
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.
117 x 788 x 861 x 990 x 224 = 17603476450560
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.
117 : 1, 3, 9, 13, 39, 117
788 : 1, 2, 4, 197, 394, 788
861 : 1, 3, 7, 21, 41, 123, 287, 861
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,788,861,990,224, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
788:2x 2x 197
861:3x 7x 41
990:2x 3x 3x 5x 11
224:2x 2x 2x 2x 2x 7
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 3x 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 17603476450560/(1x1512)
LCM = 17603476450560/1512
LCM = 11642510880
Thus, we can understand that the LCM of 117,788,861,990,224 is 11642510880.
