Find LCM of 869,975,858,955 with Prime Factorization
| 3 | 869, 975, 858, 955 |
| 5 | 869, 325, 286, 955 |
| 11 | 869, 65, 286, 191 |
| 13 | 79, 65, 26, 191 |
| 79, 5, 2, 191 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 79 x 5 x 2 x 191 = 323659050
Therefore, the lowest common multiple of 869,975,858,955 is 323659050.
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.
869 x 975 x 858 x 955 = 694248662250
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.
869 : 1, 11, 79, 869
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,975,858,955, is 1.
Now, the common factors can be found like this.
869:11x 79
975:3x 5x 5x 13
858:2x 3x 11x 13
955:5x 191
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 11x 13 = 2145
Therefore, the value for common factors is 2145.
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 = 694248662250/(1x2145)
LCM = 694248662250/2145
LCM = 323659050
Thus, we can understand that the LCM of 869,975,858,955 is 323659050.
