Given numbers are 869,713,713,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,713,713,946 is 53285342.
Find LCM of 869,713,713,946 with Prime Factorization
| 11 | 869, 713, 713, 946 |
| 23 | 79, 713, 713, 86 |
| 31 | 79, 31, 31, 86 |
| 79, 1, 1, 86 |
Multiply the prime numbers at the bottom and the left side.
11 x 23 x 31 x 79 x 1 x 1 x 86 = 53285342
Therefore, the lowest common multiple of 869,713,713,946 is 53285342.
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 713 x 713 x 946 = 417916937306
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
713 : 1, 23, 31, 713
713 : 1, 23, 31, 713
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,713,713,946, is 1.
Now, the common factors can be found like this.
869:11x 79
713:23x 31
713:23x 31
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 23x 31 = 7843
Therefore, the value for common factors is 7843.
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 = 417916937306/(1x7843)
LCM = 417916937306/7843
LCM = 53285342
Thus, we can understand that the LCM of 869,713,713,946 is 53285342.
