Given numbers are 722,308,722,253
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,308,722,253 is 2557324.
Find LCM of 722,308,722,253 with Prime Factorization
| 2 | 722, 308, 722, 253 |
| 11 | 361, 154, 361, 253 |
| 19 | 361, 14, 361, 23 |
| 19 | 19, 14, 19, 23 |
| 1, 14, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 19 x 1 x 14 x 1 x 23 = 2557324
Therefore, the lowest common multiple of 722,308,722,253 is 2557324.
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.
722 x 308 x 722 x 253 = 40620534416
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.
722 : 1, 2, 19, 38, 361, 722
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
722 : 1, 2, 19, 38, 361, 722
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,308,722,253, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
308:2x 2x 7x 11
722:2x 19x 19
253:11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 19x 19 = 15884
Therefore, the value for common factors is 15884.
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 = 40620534416/(1x15884)
LCM = 40620534416/15884
LCM = 2557324
Thus, we can understand that the LCM of 722,308,722,253 is 2557324.
