43 | 11, 1, 43, 43, 83 |
11, 1, 1, 1, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 19 x 43 x 11 x 1 x 1 x 1 x 83 = 179021040
Therefore, the lowest common multiple of 880,912,645,817,664 is 179021040.
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.
880 x 912 x 645 x 817 x 664 = 280819564185600
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.
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
645 : 1, 3, 5, 15, 43, 129, 215, 645
817 : 1, 19, 43, 817
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 880,912,645,817,664, is 1.
Now, the common factors can be found like this.
880:2x 2x 2x 2x 5x 11
912:2x 2x 2x 2x 3x 19
645:3x 5x 43
817:19x 43
664:2x 2x 2x 83
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 5x 19x 43 = 1568640
Therefore, the value for common factors is 1568640.
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 = 280819564185600/(1x1568640)
LCM = 280819564185600/1568640
LCM = 179021040
Thus, we can understand that the LCM of 880,912,645,817,664 is 179021040.
