The LCM of 741,795,880,781 is 2453777040.
Find LCM of 741,795,880,781 with Prime Factorization
| 3 | 741, 795, 880, 781 |
| 5 | 247, 265, 880, 781 |
| 11 | 247, 53, 176, 781 |
| 247, 53, 16, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 247 x 53 x 16 x 71 = 2453777040
Therefore, the lowest common multiple of 741,795,880,781 is 2453777040.
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.
741 x 795 x 880 x 781 = 404873211600
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
795 : 1, 3, 5, 15, 53, 159, 265, 795
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,795,880,781, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
795:3x 5x 53
880:2x 2x 2x 2x 5x 11
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 404873211600/(1x165)
LCM = 404873211600/165
LCM = 2453777040
Thus, we can understand that the LCM of 741,795,880,781 is 2453777040.
