Find LCM of 272,448,401,497,785 with Prime Factorization
| 2 | 272, 448, 401, 497, 785 |
| 2 | 136, 224, 401, 497, 785 |
| 2 | 68, 112, 401, 497, 785 |
| 2 | 34, 56, 401, 497, 785 |
| 7 | 17, 28, 401, 497, 785 |
| 17, 4, 401, 71, 785 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 17 x 4 x 401 x 71 x 785 = 170215581760
Therefore, the lowest common multiple of 272,448,401,497,785 is 170215581760.
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.
272 x 448 x 401 x 497 x 785 = 19064145157120
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
401 : 1, 401
497 : 1, 7, 71, 497
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,448,401,497,785, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
448:2x 2x 2x 2x 2x 2x 7
401:401
497:7x 71
785:5x 157
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 19064145157120/(1x112)
LCM = 19064145157120/112
LCM = 170215581760
Thus, we can understand that the LCM of 272,448,401,497,785 is 170215581760.
