Find LCM of 718,325,663,649,840 with Prime Factorization
2 | 718, 325, 663, 649, 840 |
3 | 359, 325, 663, 649, 420 |
5 | 359, 325, 221, 649, 140 |
13 | 359, 65, 221, 649, 28 |
359, 5, 17, 649, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 359 x 5 x 17 x 649 x 28 = 216262246200
Therefore, the lowest common multiple of 718,325,663,649,840 is 216262246200.
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.
718 x 325 x 663 x 649 x 840 = 84342276018000
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.
718 : 1, 2, 359, 718
325 : 1, 5, 13, 25, 65, 325
663 : 1, 3, 13, 17, 39, 51, 221, 663
649 : 1, 11, 59, 649
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,325,663,649,840, is 1.
Now, the common factors can be found like this.
718:2x 359
325:5x 5x 13
663:3x 13x 17
649:11x 59
840:2x 2x 2x 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 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 84342276018000/(1x390)
LCM = 84342276018000/390
LCM = 216262246200
Thus, we can understand that the LCM of 718,325,663,649,840 is 216262246200.
