Given numbers are 706,440,945,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 706,440,945,946 is 1262285640.
Find LCM of 706,440,945,946 with Prime Factorization
2 | 706, 440, 945, 946 |
5 | 353, 220, 945, 473 |
11 | 353, 44, 189, 473 |
353, 4, 189, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 353 x 4 x 189 x 43 = 1262285640
Therefore, the lowest common multiple of 706,440,945,946 is 1262285640.
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.
706 x 440 x 945 x 946 = 277702840800
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.
706 : 1, 2, 353, 706
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
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 706,440,945,946, is 1.
Now, the common factors can be found like this.
706:2x 353
440:2x 2x 2x 5x 11
945:3x 3x 3x 5x 7
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 2x 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 277702840800/(1x220)
LCM = 277702840800/220
LCM = 1262285640
Thus, we can understand that the LCM of 706,440,945,946 is 1262285640.
