| 13 | 14, 489, 13, 247, 643 |
| 14, 489, 1, 19, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 13 x 14 x 489 x 1 x 19 x 643 = 69586468224
Therefore, the lowest common multiple of 896,978,832,247,643 is 69586468224.
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.
896 x 978 x 832 x 247 x 643 = 115791883124736
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.
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
978 : 1, 2, 3, 6, 163, 326, 489, 978
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
247 : 1, 13, 19, 247
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 896,978,832,247,643, is 1.
Now, the common factors can be found like this.
896:2x 2x 2x 2x 2x 2x 2x 7
978:2x 3x 163
832:2x 2x 2x 2x 2x 2x 13
247:13x 19
643:643
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 13 = 1664
Therefore, the value for common factors is 1664.
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 = 115791883124736/(1x1664)
LCM = 115791883124736/1664
LCM = 69586468224
Thus, we can understand that the LCM of 896,978,832,247,643 is 69586468224.
