The LCM of 782,646,985,197 is 14635130.
Find LCM of 782,646,985,197 with Prime Factorization
| 2 | 782, 646, 985, 197 |
| 17 | 391, 323, 985, 197 |
| 197 | 23, 19, 985, 197 |
| 23, 19, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 197 x 23 x 19 x 5 x 1 = 14635130
Therefore, the lowest common multiple of 782,646,985,197 is 14635130.
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.
782 x 646 x 985 x 197 = 98026100740
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
646 : 1, 2, 17, 19, 34, 38, 323, 646
985 : 1, 5, 197, 985
197 : 1, 197
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,646,985,197, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
646:2x 17x 19
985:5x 197
197:197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 197 = 6698
Therefore, the value for common factors is 6698.
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 = 98026100740/(1x6698)
LCM = 98026100740/6698
LCM = 14635130
Thus, we can understand that the LCM of 782,646,985,197 is 14635130.
