Given numbers are 946,381,962,221,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 946,381,962,221,931 is 2743846367262.
Find LCM of 946,381,962,221,931 with Prime Factorization
| 2 | 946, 381, 962, 221, 931 |
| 13 | 473, 381, 481, 221, 931 |
| 473, 381, 37, 17, 931 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 473 x 381 x 37 x 17 x 931 = 2743846367262
Therefore, the lowest common multiple of 946,381,962,221,931 is 2743846367262.
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.
946 x 381 x 962 x 221 x 931 = 71340005548812
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.
946 : 1, 2, 11, 22, 43, 86, 473, 946
381 : 1, 3, 127, 381
962 : 1, 2, 13, 26, 37, 74, 481, 962
221 : 1, 13, 17, 221
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,381,962,221,931, is 1.
Now, the common factors can be found like this.
946:2x 11x 43
381:3x 127
962:2x 13x 37
221:13x 17
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 71340005548812/(1x26)
LCM = 71340005548812/26
LCM = 2743846367262
Thus, we can understand that the LCM of 946,381,962,221,931 is 2743846367262.
