Given numbers are 978,153,612,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,153,612,878 is 43792884.
Find LCM of 978,153,612,878 with Prime Factorization
2 | 978, 153, 612, 878 |
3 | 489, 153, 306, 439 |
3 | 163, 51, 102, 439 |
17 | 163, 17, 34, 439 |
163, 1, 2, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 163 x 1 x 2 x 439 = 43792884
Therefore, the lowest common multiple of 978,153,612,878 is 43792884.
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.
978 x 153 x 612 x 878 = 80403735024
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
153 : 1, 3, 9, 17, 51, 153
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,153,612,878, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
153:3x 3x 17
612:2x 2x 3x 3x 17
878:2x 439
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 3x 3x 3x 17 = 1836
Therefore, the value for common factors is 1836.
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 = 80403735024/(1x1836)
LCM = 80403735024/1836
LCM = 43792884
Thus, we can understand that the LCM of 978,153,612,878 is 43792884.
