Given numbers are 711,676,442,608
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 711,676,442,608 is 1241963424.
Find LCM of 711,676,442,608 with Prime Factorization
| 2 | 711, 676, 442, 608 |
| 2 | 711, 338, 221, 304 |
| 13 | 711, 169, 221, 152 |
| 711, 13, 17, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 711 x 13 x 17 x 152 = 1241963424
Therefore, the lowest common multiple of 711,676,442,608 is 1241963424.
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.
711 x 676 x 442 x 608 = 129164196096
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.
711 : 1, 3, 9, 79, 237, 711
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
442 : 1, 2, 13, 17, 26, 34, 221, 442
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 711,676,442,608, is 1.
Now, the common factors can be found like this.
711:3x 3x 79
676:2x 2x 13x 13
442:2x 13x 17
608:2x 2x 2x 2x 2x 19
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 13 = 104
Therefore, the value for common factors is 104.
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 = 129164196096/(1x104)
LCM = 129164196096/104
LCM = 1241963424
Thus, we can understand that the LCM of 711,676,442,608 is 1241963424.
