Given numbers are 247,957,722,435
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,957,722,435 is 44912010.
Find LCM of 247,957,722,435 with Prime Factorization
| 3 | 247, 957, 722, 435 |
| 19 | 247, 319, 722, 145 |
| 29 | 13, 319, 38, 145 |
| 13, 11, 38, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 29 x 13 x 11 x 38 x 5 = 44912010
Therefore, the lowest common multiple of 247,957,722,435 is 44912010.
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.
247 x 957 x 722 x 435 = 74239552530
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.
247 : 1, 13, 19, 247
957 : 1, 3, 11, 29, 33, 87, 319, 957
722 : 1, 2, 19, 38, 361, 722
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,957,722,435, is 1.
Now, the common factors can be found like this.
247:13x 19
957:3x 11x 29
722:2x 19x 19
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 29 = 1653
Therefore, the value for common factors is 1653.
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 = 74239552530/(1x1653)
LCM = 74239552530/1653
LCM = 44912010
Thus, we can understand that the LCM of 247,957,722,435 is 44912010.
