Given numbers are 451,981,902,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,981,902,946 is 38049066.
Find LCM of 451,981,902,946 with Prime Factorization
| 2 | 451, 981, 902, 946 |
| 11 | 451, 981, 451, 473 |
| 41 | 41, 981, 41, 43 |
| 1, 981, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 1 x 981 x 1 x 43 = 38049066
Therefore, the lowest common multiple of 451,981,902,946 is 38049066.
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.
451 x 981 x 902 x 946 = 377522832852
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.
451 : 1, 11, 41, 451
981 : 1, 3, 9, 109, 327, 981
902 : 1, 2, 11, 22, 41, 82, 451, 902
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 451,981,902,946, is 1.
Now, the common factors can be found like this.
451:11x 41
981:3x 3x 109
902:2x 11x 41
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.
2x 11x 11x 41 = 9922
Therefore, the value for common factors is 9922.
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 = 377522832852/(1x9922)
LCM = 377522832852/9922
LCM = 38049066
Thus, we can understand that the LCM of 451,981,902,946 is 38049066.
