The LCM of 882,328,778,490 is 281340360.
Find LCM of 882,328,778,490 with Prime Factorization
| 2 | 882, 328, 778, 490 |
| 7 | 441, 164, 389, 245 |
| 7 | 63, 164, 389, 35 |
| 9, 164, 389, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 9 x 164 x 389 x 5 = 281340360
Therefore, the lowest common multiple of 882,328,778,490 is 281340360.
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.
882 x 328 x 778 x 490 = 110285421120
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.
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
328 : 1, 2, 4, 8, 41, 82, 164, 328
778 : 1, 2, 389, 778
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 882,328,778,490, is 2.
Now, the common factors can be found like this.
882:2x 3x 3x 7x 7
328:2x 2x 2x 41
778:2x 389
490:2x 5x 7x 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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 110285421120/(2x196)
LCM = 110285421120/392
LCM = 281340360
Thus, we can understand that the LCM of 882,328,778,490 is 281340360.
