Given numbers are 676,345,644,552
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,345,644,552 is 3265080.
Find LCM of 676,345,644,552 with Prime Factorization
| 2 | 676, 345, 644, 552 |
| 2 | 338, 345, 322, 276 |
| 3 | 169, 345, 161, 138 |
| 23 | 169, 115, 161, 46 |
| 169, 5, 7, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 169 x 5 x 7 x 2 = 3265080
Therefore, the lowest common multiple of 676,345,644,552 is 3265080.
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.
676 x 345 x 644 x 552 = 82906911360
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
345 : 1, 3, 5, 15, 23, 69, 115, 345
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,345,644,552, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
345:3x 5x 23
644:2x 2x 7x 23
552:2x 2x 2x 3x 23
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 3x 23x 23 = 25392
Therefore, the value for common factors is 25392.
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 = 82906911360/(1x25392)
LCM = 82906911360/25392
LCM = 3265080
Thus, we can understand that the LCM of 676,345,644,552 is 3265080.
