Given numbers are 842,802,171,383,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,802,171,383,840 is 3095846250840.
Find LCM of 842,802,171,383,840 with Prime Factorization
| 2 | 842, 802, 171, 383, 840 |
| 3 | 421, 401, 171, 383, 420 |
| 421, 401, 57, 383, 140 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 421 x 401 x 57 x 383 x 140 = 3095846250840
Therefore, the lowest common multiple of 842,802,171,383,840 is 3095846250840.
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.
842 x 802 x 171 x 383 x 840 = 37150155010080
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.
842 : 1, 2, 421, 842
802 : 1, 2, 401, 802
171 : 1, 3, 9, 19, 57, 171
383 : 1, 383
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,802,171,383,840, is 1.
Now, the common factors can be found like this.
842:2x 421
802:2x 401
171:3x 3x 19
383:383
840:2x 2x 2x 3x 5x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 37150155010080/(1x12)
LCM = 37150155010080/12
LCM = 3095846250840
Thus, we can understand that the LCM of 842,802,171,383,840 is 3095846250840.
