Given numbers are 7,719,921,279
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,719,921,279 is 431091549.
Find LCM of 7,719,921,279 with Prime Factorization
| 3 | 7, 719, 921, 279 |
| 7, 719, 307, 93 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 719 x 307 x 93 = 431091549
Therefore, the lowest common multiple of 7,719,921,279 is 431091549.
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.
7 x 719 x 921 x 279 = 1293274647
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.
7 : 1, 7
719 : 1, 719
921 : 1, 3, 307, 921
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,719,921,279, is 1.
Now, the common factors can be found like this.
7:7
719:719
921:3x 307
279:3x 3x 31
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 = 1293274647/(1x3)
LCM = 1293274647/3
LCM = 431091549
Thus, we can understand that the LCM of 7,719,921,279 is 431091549.
