Find LCM of 628,299,598,441,257 with Prime Factorization
| 2 | 628, 299, 598, 441, 257 |
| 13 | 314, 299, 299, 441, 257 |
| 23 | 314, 23, 23, 441, 257 |
| 314, 1, 1, 441, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 23 x 314 x 1 x 1 x 441 x 257 = 21281515164
Therefore, the lowest common multiple of 628,299,598,441,257 is 21281515164.
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.
628 x 299 x 598 x 441 x 257 = 12726346068072
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.
628 : 1, 2, 4, 157, 314, 628
299 : 1, 13, 23, 299
598 : 1, 2, 13, 23, 26, 46, 299, 598
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,299,598,441,257, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
299:13x 23
598:2x 13x 23
441:3x 3x 7x 7
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 23 = 598
Therefore, the value for common factors is 598.
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 = 12726346068072/(1x598)
LCM = 12726346068072/598
LCM = 21281515164
Thus, we can understand that the LCM of 628,299,598,441,257 is 21281515164.
