Find LCM of 616,968,906,978,381 with Prime Factorization
| 2 | 616, 968, 906, 978, 381 |
| 2 | 308, 484, 453, 489, 381 |
| 2 | 154, 242, 453, 489, 381 |
| 3 | 77, 121, 453, 489, 381 |
| 11 | 77, 121, 151, 163, 127 |
| 7, 11, 151, 163, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 7 x 11 x 151 x 163 x 127 = 63542299128
Therefore, the lowest common multiple of 616,968,906,978,381 is 63542299128.
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.
616 x 968 x 906 x 978 x 381 = 201302003637504
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
906 : 1, 2, 3, 6, 151, 302, 453, 906
978 : 1, 2, 3, 6, 163, 326, 489, 978
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,968,906,978,381, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
968:2x 2x 2x 11x 11
906:2x 3x 151
978:2x 3x 163
381:3x 127
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 2x 2x 3x 3x 11 = 3168
Therefore, the value for common factors is 3168.
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 = 201302003637504/(1x3168)
LCM = 201302003637504/3168
LCM = 63542299128
Thus, we can understand that the LCM of 616,968,906,978,381 is 63542299128.
