Given numbers are 915,721,183,524
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,721,183,524 is 345690660.
Find LCM of 915,721,183,524 with Prime Factorization
| 3 | 915, 721, 183, 524 |
| 61 | 305, 721, 61, 524 |
| 5, 721, 1, 524 |
Multiply the prime numbers at the bottom and the left side.
3 x 61 x 5 x 721 x 1 x 524 = 345690660
Therefore, the lowest common multiple of 915,721,183,524 is 345690660.
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.
915 x 721 x 183 x 524 = 63261390780
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
721 : 1, 7, 103, 721
183 : 1, 3, 61, 183
524 : 1, 2, 4, 131, 262, 524
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,721,183,524, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
721:7x 103
183:3x 61
524:2x 2x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 61 = 183
Therefore, the value for common factors is 183.
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 = 63261390780/(1x183)
LCM = 63261390780/183
LCM = 345690660
Thus, we can understand that the LCM of 915,721,183,524 is 345690660.
