Find LCM of 905,422,774,603,790 with Prime Factorization
| 2 | 905, 422, 774, 603, 790 |
| 3 | 905, 211, 387, 603, 395 |
| 3 | 905, 211, 129, 201, 395 |
| 5 | 905, 211, 43, 67, 395 |
| 181, 211, 43, 67, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 181 x 211 x 43 x 67 x 79 = 782301006810
Therefore, the lowest common multiple of 905,422,774,603,790 is 782301006810.
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.
905 x 422 x 774 x 603 x 790 = 140814181225800
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.
905 : 1, 5, 181, 905
422 : 1, 2, 211, 422
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
603 : 1, 3, 9, 67, 201, 603
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,422,774,603,790, is 1.
Now, the common factors can be found like this.
905:5x 181
422:2x 211
774:2x 3x 3x 43
603:3x 3x 67
790:2x 5x 79
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 5 = 180
Therefore, the value for common factors is 180.
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 = 140814181225800/(1x180)
LCM = 140814181225800/180
LCM = 782301006810
Thus, we can understand that the LCM of 905,422,774,603,790 is 782301006810.
