The LCM of 703,710,689,819,644 is 996623851860.
Find LCM of 703,710,689,819,644 with Prime Factorization
| 2 | 703, 710, 689, 819, 644 |
| 7 | 703, 355, 689, 819, 322 |
| 13 | 703, 355, 689, 117, 46 |
| 703, 355, 53, 9, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 703 x 355 x 53 x 9 x 46 = 996623851860
Therefore, the lowest common multiple of 703,710,689,819,644 is 996623851860.
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.
703 x 710 x 689 x 819 x 644 = 181385541038520
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.
703 : 1, 19, 37, 703
710 : 1, 2, 5, 10, 71, 142, 355, 710
689 : 1, 13, 53, 689
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 703,710,689,819,644, is 1.
Now, the common factors can be found like this.
703:19x 37
710:2x 5x 71
689:13x 53
819:3x 3x 7x 13
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 181385541038520/(1x182)
LCM = 181385541038520/182
LCM = 996623851860
Thus, we can understand that the LCM of 703,710,689,819,644 is 996623851860.
