Find LCM of 905,672,320,869,982 with Prime Factorization
| 2 | 905, 672, 320, 869, 982 |
| 2 | 905, 336, 160, 869, 491 |
| 2 | 905, 168, 80, 869, 491 |
| 2 | 905, 84, 40, 869, 491 |
| 2 | 905, 42, 20, 869, 491 |
| 5 | 905, 21, 10, 869, 491 |
| 181, 21, 2, 869, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 181 x 21 x 2 x 869 x 491 = 518978201280
Therefore, the lowest common multiple of 905,672,320,869,982 is 518978201280.
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.
905 x 672 x 320 x 869 x 982 = 166073024409600
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.
905 : 1, 5, 181, 905
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
869 : 1, 11, 79, 869
982 : 1, 2, 491, 982
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,672,320,869,982, is 1.
Now, the common factors can be found like this.
905:5x 181
672:2x 2x 2x 2x 2x 3x 7
320:2x 2x 2x 2x 2x 2x 5
869:11x 79
982:2x 491
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 2x 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 166073024409600/(1x320)
LCM = 166073024409600/320
LCM = 518978201280
Thus, we can understand that the LCM of 905,672,320,869,982 is 518978201280.
