Find LCM of 815,237,954,480,786 with Prime Factorization
2 | 815, 237, 954, 480, 786 |
3 | 815, 237, 477, 240, 393 |
5 | 815, 79, 159, 80, 131 |
163, 79, 159, 16, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 163 x 79 x 159 x 16 x 131 = 128743215840
Therefore, the lowest common multiple of 815,237,954,480,786 is 128743215840.
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.
815 x 237 x 954 x 480 x 786 = 69521336553600
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.
815 : 1, 5, 163, 815
237 : 1, 3, 79, 237
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,237,954,480,786, is 1.
Now, the common factors can be found like this.
815:5x 163
237:3x 79
954:2x 3x 3x 53
480:2x 2x 2x 2x 2x 3x 5
786:2x 3x 131
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 69521336553600/(1x540)
LCM = 69521336553600/540
LCM = 128743215840
Thus, we can understand that the LCM of 815,237,954,480,786 is 128743215840.
