| 13 | 83, 117, 5, 23, 13 |
| 83, 9, 5, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 13 x 83 x 9 x 5 x 23 x 1 = 2063781720
Therefore, the lowest common multiple of 913,702,840,506,728 is 2063781720.
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.
913 x 702 x 840 x 506 x 728 = 198321168165120
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.
913 : 1, 11, 83, 913
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
506 : 1, 2, 11, 22, 23, 46, 253, 506
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,702,840,506,728, is 1.
Now, the common factors can be found like this.
913:11x 83
702:2x 3x 3x 3x 13
840:2x 2x 2x 3x 5x 7
506:2x 11x 23
728:2x 2x 2x 7x 13
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 3x 7x 11x 13 = 96096
Therefore, the value for common factors is 96096.
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 = 198321168165120/(1x96096)
LCM = 198321168165120/96096
LCM = 2063781720
Thus, we can understand that the LCM of 913,702,840,506,728 is 2063781720.
