Given numbers are 103,976,728,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,976,728,678 is 3101188272.
Find LCM of 103,976,728,678 with Prime Factorization
2 | 103, 976, 728, 678 |
2 | 103, 488, 364, 339 |
2 | 103, 244, 182, 339 |
103, 122, 91, 339 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 103 x 122 x 91 x 339 = 3101188272
Therefore, the lowest common multiple of 103,976,728,678 is 3101188272.
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.
103 x 976 x 728 x 678 = 49619012352
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.
103 : 1, 103
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,976,728,678, is 1.
Now, the common factors can be found like this.
103:103
976:2x 2x 2x 2x 61
728:2x 2x 2x 7x 13
678:2x 3x 113
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 2 = 16
Therefore, the value for common factors is 16.
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 = 49619012352/(1x16)
LCM = 49619012352/16
LCM = 3101188272
Thus, we can understand that the LCM of 103,976,728,678 is 3101188272.
