Find LCM of 869,774,671,388,387 with Prime Factorization
2 | 869, 774, 671, 388, 387 |
3 | 869, 387, 671, 194, 387 |
3 | 869, 129, 671, 194, 129 |
11 | 869, 43, 671, 194, 43 |
43 | 79, 43, 61, 194, 43 |
79, 1, 61, 194, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 43 x 79 x 1 x 61 x 194 x 1 = 7959619404
Therefore, the lowest common multiple of 869,774,671,388,387 is 7959619404.
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.
869 x 774 x 671 x 388 x 387 = 67768199605656
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.
869 : 1, 11, 79, 869
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
671 : 1, 11, 61, 671
388 : 1, 2, 4, 97, 194, 388
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,774,671,388,387, is 1.
Now, the common factors can be found like this.
869:11x 79
774:2x 3x 3x 43
671:11x 61
388:2x 2x 97
387:3x 3x 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 3x 3x 11x 43 = 8514
Therefore, the value for common factors is 8514.
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 = 67768199605656/(1x8514)
LCM = 67768199605656/8514
LCM = 7959619404
Thus, we can understand that the LCM of 869,774,671,388,387 is 7959619404.
