The LCM of 649,918,310,170,271 is 25025822910.
Find LCM of 649,918,310,170,271 with Prime Factorization
| 2 | 649, 918, 310, 170, 271 |
| 5 | 649, 459, 155, 85, 271 |
| 17 | 649, 459, 31, 17, 271 |
| 649, 27, 31, 1, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 649 x 27 x 31 x 1 x 271 = 25025822910
Therefore, the lowest common multiple of 649,918,310,170,271 is 25025822910.
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.
649 x 918 x 310 x 170 x 271 = 8508779789400
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.
649 : 1, 11, 59, 649
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
310 : 1, 2, 5, 10, 31, 62, 155, 310
170 : 1, 2, 5, 10, 17, 34, 85, 170
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,918,310,170,271, is 1.
Now, the common factors can be found like this.
649:11x 59
918:2x 3x 3x 3x 17
310:2x 5x 31
170:2x 5x 17
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 8508779789400/(1x340)
LCM = 8508779789400/340
LCM = 25025822910
Thus, we can understand that the LCM of 649,918,310,170,271 is 25025822910.
