Find LCM of 821,778,858,819,336 with Prime Factorization
| 2 | 821, 778, 858, 819, 336 |
| 3 | 821, 389, 429, 819, 168 |
| 7 | 821, 389, 143, 273, 56 |
| 13 | 821, 389, 143, 39, 8 |
| 821, 389, 11, 3, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 821 x 389 x 11 x 3 x 8 = 46035125136
Therefore, the lowest common multiple of 821,778,858,819,336 is 46035125136.
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.
821 x 778 x 858 x 819 x 336 = 150811069945536
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.
821 : 1, 821
778 : 1, 2, 389, 778
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,778,858,819,336, is 1.
Now, the common factors can be found like this.
821:821
778:2x 389
858:2x 3x 11x 13
819:3x 3x 7x 13
336:2x 2x 2x 2x 3x 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 2x 3x 3x 7x 13 = 3276
Therefore, the value for common factors is 3276.
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 = 150811069945536/(1x3276)
LCM = 150811069945536/3276
LCM = 46035125136
Thus, we can understand that the LCM of 821,778,858,819,336 is 46035125136.
