Find LCM of 819,825,190,611,715 with Prime Factorization
| 3 | 819, 825, 190, 611, 715 |
| 5 | 273, 275, 190, 611, 715 |
| 11 | 273, 55, 38, 611, 143 |
| 13 | 273, 5, 38, 611, 13 |
| 21, 5, 38, 47, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 21 x 5 x 38 x 47 x 1 = 402251850
Therefore, the lowest common multiple of 819,825,190,611,715 is 402251850.
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.
819 x 825 x 190 x 611 x 715 = 56083964186250
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
190 : 1, 2, 5, 10, 19, 38, 95, 190
611 : 1, 13, 47, 611
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,825,190,611,715, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
825:3x 5x 5x 11
190:2x 5x 19
611:13x 47
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11x 13x 13 = 139425
Therefore, the value for common factors is 139425.
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 = 56083964186250/(1x139425)
LCM = 56083964186250/139425
LCM = 402251850
Thus, we can understand that the LCM of 819,825,190,611,715 is 402251850.
