Find LCM of 845,644,379,966,655 with Prime Factorization
| 2 | 845, 644, 379, 966, 655 |
| 5 | 845, 322, 379, 483, 655 |
| 7 | 169, 322, 379, 483, 131 |
| 23 | 169, 46, 379, 69, 131 |
| 169, 2, 379, 3, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 23 x 169 x 2 x 379 x 3 x 131 = 81053978460
Therefore, the lowest common multiple of 845,644,379,966,655 is 81053978460.
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.
845 x 644 x 379 x 966 x 655 = 130496905320600
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.
845 : 1, 5, 13, 65, 169, 845
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
379 : 1, 379
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,644,379,966,655, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
644:2x 2x 7x 23
379:379
966:2x 3x 7x 23
655:5x 131
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 7x 23 = 1610
Therefore, the value for common factors is 1610.
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 = 130496905320600/(1x1610)
LCM = 130496905320600/1610
LCM = 81053978460
Thus, we can understand that the LCM of 845,644,379,966,655 is 81053978460.
