Given numbers are 672,677,828,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,677,828,556 is 4363367904.
Find LCM of 672,677,828,556 with Prime Factorization
| 2 | 672, 677, 828, 556 |
| 2 | 336, 677, 414, 278 |
| 3 | 168, 677, 207, 139 |
| 56, 677, 69, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 56 x 677 x 69 x 139 = 4363367904
Therefore, the lowest common multiple of 672,677,828,556 is 4363367904.
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.
672 x 677 x 828 x 556 = 209441659392
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
677 : 1, 677
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
556 : 1, 2, 4, 139, 278, 556
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,677,828,556, is 1.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
677:677
828:2x 2x 3x 3x 23
556:2x 2x 139
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 3 = 48
Therefore, the value for common factors is 48.
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 = 209441659392/(1x48)
LCM = 209441659392/48
LCM = 4363367904
Thus, we can understand that the LCM of 672,677,828,556 is 4363367904.
