Given numbers are 721,539,957,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,539,957,147 is 4829979.
Find LCM of 721,539,957,147 with Prime Factorization
| 3 | 721, 539, 957, 147 |
| 7 | 721, 539, 319, 49 |
| 7 | 103, 77, 319, 7 |
| 11 | 103, 11, 319, 1 |
| 103, 1, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 7 x 11 x 103 x 1 x 29 x 1 = 4829979
Therefore, the lowest common multiple of 721,539,957,147 is 4829979.
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.
721 x 539 x 957 x 147 = 54670532301
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.
721 : 1, 7, 103, 721
539 : 1, 7, 11, 49, 77, 539
957 : 1, 3, 11, 29, 33, 87, 319, 957
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,539,957,147, is 1.
Now, the common factors can be found like this.
721:7x 103
539:7x 7x 11
957:3x 11x 29
147:3x 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.
3x 7x 7x 7x 11 = 11319
Therefore, the value for common factors is 11319.
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 = 54670532301/(1x11319)
LCM = 54670532301/11319
LCM = 4829979
Thus, we can understand that the LCM of 721,539,957,147 is 4829979.
