Find LCM of 787,163,664,246,656 with Prime Factorization
2 | 787, 163, 664, 246, 656 |
2 | 787, 163, 332, 123, 328 |
2 | 787, 163, 166, 123, 164 |
41 | 787, 163, 83, 123, 82 |
787, 163, 83, 3, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 41 x 787 x 163 x 83 x 3 x 2 = 20953931664
Therefore, the lowest common multiple of 787,163,664,246,656 is 20953931664.
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.
787 x 163 x 664 x 246 x 656 = 13745779171584
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.
787 : 1, 787
163 : 1, 163
664 : 1, 2, 4, 8, 83, 166, 332, 664
246 : 1, 2, 3, 6, 41, 82, 123, 246
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,163,664,246,656, is 1.
Now, the common factors can be found like this.
787:787
163:163
664:2x 2x 2x 83
246:2x 3x 41
656:2x 2x 2x 2x 41
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 41 = 656
Therefore, the value for common factors is 656.
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 = 13745779171584/(1x656)
LCM = 13745779171584/656
LCM = 20953931664
Thus, we can understand that the LCM of 787,163,664,246,656 is 20953931664.
