The LCM of 714,520,819,561 is 6126120.
Find LCM of 714,520,819,561 with Prime Factorization
| 2 | 714, 520, 819, 561 |
| 3 | 357, 260, 819, 561 |
| 7 | 119, 260, 273, 187 |
| 13 | 17, 260, 39, 187 |
| 17 | 17, 20, 3, 187 |
| 1, 20, 3, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 17 x 1 x 20 x 3 x 11 = 6126120
Therefore, the lowest common multiple of 714,520,819,561 is 6126120.
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.
714 x 520 x 819 x 561 = 170587937520
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,520,819,561, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
520:2x 2x 2x 5x 13
819:3x 3x 7x 13
561:3x 11x 17
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 3x 7x 13x 17 = 27846
Therefore, the value for common factors is 27846.
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 = 170587937520/(1x27846)
LCM = 170587937520/27846
LCM = 6126120
Thus, we can understand that the LCM of 714,520,819,561 is 6126120.
