Given numbers are 878,325,899,611,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 878,325,899,611,990 is 1193632461450.
Find LCM of 878,325,899,611,990 with Prime Factorization
| 2 | 878, 325, 899, 611, 990 |
| 5 | 439, 325, 899, 611, 495 |
| 13 | 439, 65, 899, 611, 99 |
| 439, 5, 899, 47, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 439 x 5 x 899 x 47 x 99 = 1193632461450
Therefore, the lowest common multiple of 878,325,899,611,990 is 1193632461450.
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.
878 x 325 x 899 x 611 x 990 = 155172219988500
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.
878 : 1, 2, 439, 878
325 : 1, 5, 13, 25, 65, 325
899 : 1, 29, 31, 899
611 : 1, 13, 47, 611
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,325,899,611,990, is 1.
Now, the common factors can be found like this.
878:2x 439
325:5x 5x 13
899:29x 31
611:13x 47
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 155172219988500/(1x130)
LCM = 155172219988500/130
LCM = 1193632461450
Thus, we can understand that the LCM of 878,325,899,611,990 is 1193632461450.
