| 5 | 17, 755, 124, 49, 35 |
| 7 | 17, 151, 124, 49, 7 |
| 17, 151, 124, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 5 x 7 x 17 x 151 x 124 x 1 x 7 = 16844859360
Therefore, the lowest common multiple of 459,755,992,392,945 is 16844859360.
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.
459 x 755 x 992 x 392 x 945 = 127347136761600
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
755 : 1, 5, 151, 755
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,755,992,392,945, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
755:5x 151
992:2x 2x 2x 2x 2x 31
392:2x 2x 2x 7x 7
945:3x 3x 3x 5x 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 5x 7 = 7560
Therefore, the value for common factors is 7560.
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 = 127347136761600/(1x7560)
LCM = 127347136761600/7560
LCM = 16844859360
Thus, we can understand that the LCM of 459,755,992,392,945 is 16844859360.
