Given numbers are 398,395,850,442,797
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,395,850,442,797 is 138452488850.
Find LCM of 398,395,850,442,797 with Prime Factorization
2 | 398, 395, 850, 442, 797 |
5 | 199, 395, 425, 221, 797 |
17 | 199, 79, 85, 221, 797 |
199, 79, 5, 13, 797 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 199 x 79 x 5 x 13 x 797 = 138452488850
Therefore, the lowest common multiple of 398,395,850,442,797 is 138452488850.
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.
398 x 395 x 850 x 442 x 797 = 47073846209000
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.
398 : 1, 2, 199, 398
395 : 1, 5, 79, 395
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
442 : 1, 2, 13, 17, 26, 34, 221, 442
797 : 1, 797
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,395,850,442,797, is 1.
Now, the common factors can be found like this.
398:2x 199
395:5x 79
850:2x 5x 5x 17
442:2x 13x 17
797:797
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 47073846209000/(1x340)
LCM = 47073846209000/340
LCM = 138452488850
Thus, we can understand that the LCM of 398,395,850,442,797 is 138452488850.
