Find LCM of 845,418,990,962 with Prime Factorization
2 | 845, 418, 990, 962 |
5 | 845, 209, 495, 481 |
11 | 169, 209, 99, 481 |
13 | 169, 19, 9, 481 |
13, 19, 9, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 13 x 19 x 9 x 37 = 117618930
Therefore, the lowest common multiple of 845,418,990,962 is 117618930.
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.
845 x 418 x 990 x 962 = 336390139800
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.
845 : 1, 5, 13, 65, 169, 845
418 : 1, 2, 11, 19, 22, 38, 209, 418
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
962 : 1, 2, 13, 26, 37, 74, 481, 962
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,418,990,962, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
418:2x 11x 19
990:2x 3x 3x 5x 11
962:2x 13x 37
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 5x 11x 13 = 2860
Therefore, the value for common factors is 2860.
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 = 336390139800/(1x2860)
LCM = 336390139800/2860
LCM = 117618930
Thus, we can understand that the LCM of 845,418,990,962 is 117618930.
