Given numbers are 831,725,169,498,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,725,169,498,980 is 1656379697700.
Find LCM of 831,725,169,498,980 with Prime Factorization
| 2 | 831, 725, 169, 498, 980 |
| 3 | 831, 725, 169, 249, 490 |
| 5 | 277, 725, 169, 83, 490 |
| 277, 145, 169, 83, 98 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 277 x 145 x 169 x 83 x 98 = 1656379697700
Therefore, the lowest common multiple of 831,725,169,498,980 is 1656379697700.
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.
831 x 725 x 169 x 498 x 980 = 49691390931000
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.
831 : 1, 3, 277, 831
725 : 1, 5, 25, 29, 145, 725
169 : 1, 13, 169
498 : 1, 2, 3, 6, 83, 166, 249, 498
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 831,725,169,498,980, is 1.
Now, the common factors can be found like this.
831:3x 277
725:5x 5x 29
169:13x 13
498:2x 3x 83
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 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 49691390931000/(1x30)
LCM = 49691390931000/30
LCM = 1656379697700
Thus, we can understand that the LCM of 831,725,169,498,980 is 1656379697700.
