Given numbers are 691,346,519,447,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,346,519,447,747 is 26610989058.
Find LCM of 691,346,519,447,747 with Prime Factorization
| 3 | 691, 346, 519, 447, 747 |
| 173 | 691, 346, 173, 149, 249 |
| 691, 2, 1, 149, 249 |
Multiply the prime numbers at the bottom and the left side.
3 x 173 x 691 x 2 x 1 x 149 x 249 = 26610989058
Therefore, the lowest common multiple of 691,346,519,447,747 is 26610989058.
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.
691 x 346 x 519 x 447 x 747 = 41433309963306
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.
691 : 1, 691
346 : 1, 2, 173, 346
519 : 1, 3, 173, 519
447 : 1, 3, 149, 447
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,346,519,447,747, is 1.
Now, the common factors can be found like this.
691:691
346:2x 173
519:3x 173
447:3x 149
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 173 = 1557
Therefore, the value for common factors is 1557.
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 = 41433309963306/(1x1557)
LCM = 41433309963306/1557
LCM = 26610989058
Thus, we can understand that the LCM of 691,346,519,447,747 is 26610989058.
