Given numbers are 742,111,777,691,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,111,777,691,441 is 1195154982.
Find LCM of 742,111,777,691,441 with Prime Factorization
| 3 | 742, 111, 777, 691, 441 |
| 7 | 742, 37, 259, 691, 147 |
| 37 | 106, 37, 37, 691, 21 |
| 106, 1, 1, 691, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 37 x 106 x 1 x 1 x 691 x 21 = 1195154982
Therefore, the lowest common multiple of 742,111,777,691,441 is 1195154982.
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.
742 x 111 x 777 x 691 x 441 = 19501343841294
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
111 : 1, 3, 37, 111
777 : 1, 3, 7, 21, 37, 111, 259, 777
691 : 1, 691
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,111,777,691,441, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
111:3x 37
777:3x 7x 37
691:691
441:3x 3x 7x 7
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 7x 7x 37 = 16317
Therefore, the value for common factors is 16317.
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 = 19501343841294/(1x16317)
LCM = 19501343841294/16317
LCM = 1195154982
Thus, we can understand that the LCM of 742,111,777,691,441 is 1195154982.
