Given numbers are 398,758,758,789,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,758,758,789,346 is 20589480474.
Find LCM of 398,758,758,789,346 with Prime Factorization
2 | 398, 758, 758, 789, 346 |
379 | 199, 379, 379, 789, 173 |
199, 1, 1, 789, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 379 x 199 x 1 x 1 x 789 x 173 = 20589480474
Therefore, the lowest common multiple of 398,758,758,789,346 is 20589480474.
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 758 x 758 x 789 x 346 = 62427304797168
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
758 : 1, 2, 379, 758
758 : 1, 2, 379, 758
789 : 1, 3, 263, 789
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,758,758,789,346, is 1.
Now, the common factors can be found like this.
398:2x 199
758:2x 379
758:2x 379
789:3x 263
346:2x 173
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 2x 379 = 3032
Therefore, the value for common factors is 3032.
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 = 62427304797168/(1x3032)
LCM = 62427304797168/3032
LCM = 20589480474
Thus, we can understand that the LCM of 398,758,758,789,346 is 20589480474.
