Find LCM of 655,910,815,322,230 with Prime Factorization
2 | 655, 910, 815, 322, 230 |
5 | 655, 455, 815, 161, 115 |
7 | 131, 91, 163, 161, 23 |
23 | 131, 13, 163, 23, 23 |
131, 13, 163, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 131 x 13 x 163 x 1 x 1 = 446918290
Therefore, the lowest common multiple of 655,910,815,322,230 is 446918290.
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.
655 x 910 x 815 x 322 x 230 = 35976922345000
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.
655 : 1, 5, 131, 655
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
815 : 1, 5, 163, 815
322 : 1, 2, 7, 14, 23, 46, 161, 322
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,910,815,322,230, is 1.
Now, the common factors can be found like this.
655:5x 131
910:2x 5x 7x 13
815:5x 163
322:2x 7x 23
230:2x 5x 23
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 5x 5x 7x 23 = 80500
Therefore, the value for common factors is 80500.
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 = 35976922345000/(1x80500)
LCM = 35976922345000/80500
LCM = 446918290
Thus, we can understand that the LCM of 655,910,815,322,230 is 446918290.
