The LCM of 217,950,138,465,649 is 9231603150.
Find LCM of 217,950,138,465,649 with Prime Factorization
| 2 | 217, 950, 138, 465, 649 |
| 3 | 217, 475, 69, 465, 649 |
| 5 | 217, 475, 23, 155, 649 |
| 31 | 217, 95, 23, 31, 649 |
| 7, 95, 23, 1, 649 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 7 x 95 x 23 x 1 x 649 = 9231603150
Therefore, the lowest common multiple of 217,950,138,465,649 is 9231603150.
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.
217 x 950 x 138 x 465 x 649 = 8585390929500
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.
217 : 1, 7, 31, 217
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
138 : 1, 2, 3, 6, 23, 46, 69, 138
465 : 1, 3, 5, 15, 31, 93, 155, 465
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,950,138,465,649, is 1.
Now, the common factors can be found like this.
217:7x 31
950:2x 5x 5x 19
138:2x 3x 23
465:3x 5x 31
649:11x 59
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 5x 31 = 930
Therefore, the value for common factors is 930.
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 = 8585390929500/(1x930)
LCM = 8585390929500/930
LCM = 9231603150
Thus, we can understand that the LCM of 217,950,138,465,649 is 9231603150.
