Given numbers are 839,424,785,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,424,785,146 is 20385451480.
Find LCM of 839,424,785,146 with Prime Factorization
2 | 839, 424, 785, 146 |
839, 212, 785, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 839 x 212 x 785 x 73 = 20385451480
Therefore, the lowest common multiple of 839,424,785,146 is 20385451480.
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.
839 x 424 x 785 x 146 = 40770902960
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.
839 : 1, 839
424 : 1, 2, 4, 8, 53, 106, 212, 424
785 : 1, 5, 157, 785
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,424,785,146, is 1.
Now, the common factors can be found like this.
839:839
424:2x 2x 2x 53
785:5x 157
146:2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 40770902960/(1x2)
LCM = 40770902960/2
LCM = 20385451480
Thus, we can understand that the LCM of 839,424,785,146 is 20385451480.
