Given numbers are 629,831,820,235,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,831,820,235,980 is 987096153540.
Find LCM of 629,831,820,235,980 with Prime Factorization
| 2 | 629, 831, 820, 235, 980 |
| 2 | 629, 831, 410, 235, 490 |
| 5 | 629, 831, 205, 235, 245 |
| 629, 831, 41, 47, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 629 x 831 x 41 x 47 x 49 = 987096153540
Therefore, the lowest common multiple of 629,831,820,235,980 is 987096153540.
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.
629 x 831 x 820 x 235 x 980 = 98709615354000
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.
629 : 1, 17, 37, 629
831 : 1, 3, 277, 831
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
235 : 1, 5, 47, 235
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,831,820,235,980, is 1.
Now, the common factors can be found like this.
629:17x 37
831:3x 277
820:2x 2x 5x 41
235:5x 47
980:2x 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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 98709615354000/(1x100)
LCM = 98709615354000/100
LCM = 987096153540
Thus, we can understand that the LCM of 629,831,820,235,980 is 987096153540.
