Find LCM of 644,889,357,954,256 with Prime Factorization
2 | 644, 889, 357, 954, 256 |
2 | 322, 889, 357, 477, 128 |
3 | 161, 889, 357, 477, 64 |
7 | 161, 889, 119, 159, 64 |
23, 127, 17, 159, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 23 x 127 x 17 x 159 x 64 = 42446009088
Therefore, the lowest common multiple of 644,889,357,954,256 is 42446009088.
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.
644 x 889 x 357 x 954 x 256 = 49916506687488
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
889 : 1, 7, 127, 889
357 : 1, 3, 7, 17, 21, 51, 119, 357
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,889,357,954,256, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
889:7x 127
357:3x 7x 17
954:2x 3x 3x 53
256:2x 2x 2x 2x 2x 2x 2x 2
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 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 49916506687488/(1x1176)
LCM = 49916506687488/1176
LCM = 42446009088
Thus, we can understand that the LCM of 644,889,357,954,256 is 42446009088.
