Given numbers are 470,330,935,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,330,935,781 is 18720570.
Find LCM of 470,330,935,781 with Prime Factorization
2 | 470, 330, 935, 781 |
5 | 235, 165, 935, 781 |
11 | 47, 33, 187, 781 |
47, 3, 17, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 47 x 3 x 17 x 71 = 18720570
Therefore, the lowest common multiple of 470,330,935,781 is 18720570.
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.
470 x 330 x 935 x 781 = 113259448500
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
935 : 1, 5, 11, 17, 55, 85, 187, 935
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,330,935,781, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
330:2x 3x 5x 11
935:5x 11x 17
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 11 = 6050
Therefore, the value for common factors is 6050.
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 = 113259448500/(1x6050)
LCM = 113259448500/6050
LCM = 18720570
Thus, we can understand that the LCM of 470,330,935,781 is 18720570.
