The LCM of 110,420,361,173,855 is 865598580.
Find LCM of 110,420,361,173,855 with Prime Factorization
| 2 | 110, 420, 361, 173, 855 |
| 3 | 55, 210, 361, 173, 855 |
| 5 | 55, 70, 361, 173, 285 |
| 19 | 11, 14, 361, 173, 57 |
| 11, 14, 19, 173, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 11 x 14 x 19 x 173 x 3 = 865598580
Therefore, the lowest common multiple of 110,420,361,173,855 is 865598580.
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.
110 x 420 x 361 x 173 x 855 = 2466955953000
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.
110 : 1, 2, 5, 10, 11, 22, 55, 110
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
361 : 1, 19, 361
173 : 1, 173
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 110,420,361,173,855, is 1.
Now, the common factors can be found like this.
110:2x 5x 11
420:2x 2x 3x 5x 7
361:19x 19
173:173
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 19 = 2850
Therefore, the value for common factors is 2850.
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 = 2466955953000/(1x2850)
LCM = 2466955953000/2850
LCM = 865598580
Thus, we can understand that the LCM of 110,420,361,173,855 is 865598580.
