Given numbers are 721,939,362,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,939,362,957 is 78180800082.
Find LCM of 721,939,362,957 with Prime Factorization
| 3 | 721, 939, 362, 957 |
| 721, 313, 362, 319 |
Multiply the prime numbers at the bottom and the left side.
3 x 721 x 313 x 362 x 319 = 78180800082
Therefore, the lowest common multiple of 721,939,362,957 is 78180800082.
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 939 x 362 x 957 = 234542400246
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
939 : 1, 3, 313, 939
362 : 1, 2, 181, 362
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,939,362,957, is 1.
Now, the common factors can be found like this.
721:7x 103
939:3x 313
362:2x 181
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 234542400246/(1x3)
LCM = 234542400246/3
LCM = 78180800082
Thus, we can understand that the LCM of 721,939,362,957 is 78180800082.
