The LCM of 649,945,710,238,169 is 250207587630.
Find LCM of 649,945,710,238,169 with Prime Factorization
| 2 | 649, 945, 710, 238, 169 |
| 5 | 649, 945, 355, 119, 169 |
| 7 | 649, 189, 71, 119, 169 |
| 649, 27, 71, 17, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 649 x 27 x 71 x 17 x 169 = 250207587630
Therefore, the lowest common multiple of 649,945,710,238,169 is 250207587630.
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 945 x 710 x 238 x 169 = 17514531134100
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
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
710 : 1, 2, 5, 10, 71, 142, 355, 710
238 : 1, 2, 7, 14, 17, 34, 119, 238
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,945,710,238,169, is 1.
Now, the common factors can be found like this.
649:11x 59
945:3x 3x 3x 5x 7
710:2x 5x 71
238:2x 7x 17
169:13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 17514531134100/(1x70)
LCM = 17514531134100/70
LCM = 250207587630
Thus, we can understand that the LCM of 649,945,710,238,169 is 250207587630.
