Given numbers are 998,611,860,256,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,611,860,256,345 is 1157895248640.
Find LCM of 998,611,860,256,345 with Prime Factorization
| 2 | 998, 611, 860, 256, 345 |
| 2 | 499, 611, 430, 128, 345 |
| 5 | 499, 611, 215, 64, 345 |
| 499, 611, 43, 64, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 499 x 611 x 43 x 64 x 69 = 1157895248640
Therefore, the lowest common multiple of 998,611,860,256,345 is 1157895248640.
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.
998 x 611 x 860 x 256 x 345 = 46315809945600
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.
998 : 1, 2, 499, 998
611 : 1, 13, 47, 611
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,611,860,256,345, is 1.
Now, the common factors can be found like this.
998:2x 499
611:13x 47
860:2x 2x 5x 43
256:2x 2x 2x 2x 2x 2x 2x 2
345:3x 5x 23
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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 46315809945600/(1x40)
LCM = 46315809945600/40
LCM = 1157895248640
Thus, we can understand that the LCM of 998,611,860,256,345 is 1157895248640.
