Find LCM of 812,532,845,869,121 with Prime Factorization
| 2 | 812, 532, 845, 869, 121 |
| 2 | 406, 266, 845, 869, 121 |
| 7 | 203, 133, 845, 869, 121 |
| 11 | 29, 19, 845, 869, 121 |
| 29, 19, 845, 79, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 29 x 19 x 845 x 79 x 11 = 124617432940
Therefore, the lowest common multiple of 812,532,845,869,121 is 124617432940.
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.
812 x 532 x 845 x 869 x 121 = 38382169345520
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
845 : 1, 5, 13, 65, 169, 845
869 : 1, 11, 79, 869
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,532,845,869,121, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
532:2x 2x 7x 19
845:5x 13x 13
869:11x 79
121:11x 11
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 38382169345520/(1x308)
LCM = 38382169345520/308
LCM = 124617432940
Thus, we can understand that the LCM of 812,532,845,869,121 is 124617432940.
