Given numbers are 949,390,443,721,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 949,390,443,721,939 is 2846235267330.
Find LCM of 949,390,443,721,939 with Prime Factorization
| 3 | 949, 390, 443, 721, 939 |
| 13 | 949, 130, 443, 721, 313 |
| 73, 10, 443, 721, 313 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 73 x 10 x 443 x 721 x 313 = 2846235267330
Therefore, the lowest common multiple of 949,390,443,721,939 is 2846235267330.
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.
949 x 390 x 443 x 721 x 939 = 111003175425870
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.
949 : 1, 13, 73, 949
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
443 : 1, 443
721 : 1, 7, 103, 721
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 949,390,443,721,939, is 1.
Now, the common factors can be found like this.
949:13x 73
390:2x 3x 5x 13
443:443
721:7x 103
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 111003175425870/(1x39)
LCM = 111003175425870/39
LCM = 2846235267330
Thus, we can understand that the LCM of 949,390,443,721,939 is 2846235267330.
