Given numbers are 390,517,821,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,517,821,474 is 13077520170.
Find LCM of 390,517,821,474 with Prime Factorization
2 | 390, 517, 821, 474 |
3 | 195, 517, 821, 237 |
65, 517, 821, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 65 x 517 x 821 x 79 = 13077520170
Therefore, the lowest common multiple of 390,517,821,474 is 13077520170.
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.
390 x 517 x 821 x 474 = 78465121020
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
517 : 1, 11, 47, 517
821 : 1, 821
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,517,821,474, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
517:11x 47
821:821
474:2x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 78465121020/(1x6)
LCM = 78465121020/6
LCM = 13077520170
Thus, we can understand that the LCM of 390,517,821,474 is 13077520170.
