Find LCM of 342,685,861,137,651 with Prime Factorization
| 3 | 342, 685, 861, 137, 651 |
| 7 | 114, 685, 287, 137, 217 |
| 137 | 114, 685, 41, 137, 31 |
| 114, 5, 41, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 137 x 114 x 5 x 41 x 1 x 31 = 2084300190
Therefore, the lowest common multiple of 342,685,861,137,651 is 2084300190.
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.
342 x 685 x 861 x 137 x 651 = 17989594939890
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
685 : 1, 5, 137, 685
861 : 1, 3, 7, 21, 41, 123, 287, 861
137 : 1, 137
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,685,861,137,651, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
685:5x 137
861:3x 7x 41
137:137
651:3x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 137 = 8631
Therefore, the value for common factors is 8631.
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 = 17989594939890/(1x8631)
LCM = 17989594939890/8631
LCM = 2084300190
Thus, we can understand that the LCM of 342,685,861,137,651 is 2084300190.
