Find LCM of 978,856,342,722,163 with Prime Factorization
2 | 978, 856, 342, 722, 163 |
3 | 489, 428, 171, 361, 163 |
19 | 163, 428, 57, 361, 163 |
163 | 163, 428, 3, 19, 163 |
1, 428, 3, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 163 x 1 x 428 x 3 x 19 x 1 = 453326472
Therefore, the lowest common multiple of 978,856,342,722,163 is 453326472.
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 856 x 342 x 722 x 163 = 33694850010816
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
722 : 1, 2, 19, 38, 361, 722
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,856,342,722,163, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
856:2x 2x 2x 107
342:2x 3x 3x 19
722:2x 19x 19
163:163
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 3x 19x 163 = 74328
Therefore, the value for common factors is 74328.
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 = 33694850010816/(1x74328)
LCM = 33694850010816/74328
LCM = 453326472
Thus, we can understand that the LCM of 978,856,342,722,163 is 453326472.
