Given numbers are 943,406,261,789,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 943,406,261,789,128 is 57998392704.
Find LCM of 943,406,261,789,128 with Prime Factorization
2 | 943, 406, 261, 789, 128 |
3 | 943, 203, 261, 789, 64 |
29 | 943, 203, 87, 263, 64 |
943, 7, 3, 263, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 943 x 7 x 3 x 263 x 64 = 57998392704
Therefore, the lowest common multiple of 943,406,261,789,128 is 57998392704.
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.
943 x 406 x 261 x 789 x 128 = 10091720330496
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.
943 : 1, 23, 41, 943
406 : 1, 2, 7, 14, 29, 58, 203, 406
261 : 1, 3, 9, 29, 87, 261
789 : 1, 3, 263, 789
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 943,406,261,789,128, is 1.
Now, the common factors can be found like this.
943:23x 41
406:2x 7x 29
261:3x 3x 29
789:3x 263
128:2x 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 3x 29 = 174
Therefore, the value for common factors is 174.
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 = 10091720330496/(1x174)
LCM = 10091720330496/174
LCM = 57998392704
Thus, we can understand that the LCM of 943,406,261,789,128 is 57998392704.
