Find LCM of 398,491,216,243,148 with Prime Factorization
| 2 | 398, 491, 216, 243, 148 |
| 2 | 199, 491, 108, 243, 74 |
| 3 | 199, 491, 54, 243, 37 |
| 3 | 199, 491, 18, 81, 37 |
| 3 | 199, 491, 6, 27, 37 |
| 199, 491, 2, 9, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 199 x 491 x 2 x 9 x 37 = 7028012952
Therefore, the lowest common multiple of 398,491,216,243,148 is 7028012952.
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.
398 x 491 x 216 x 243 x 148 = 1518050797632
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.
398 : 1, 2, 199, 398
491 : 1, 491
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
243 : 1, 3, 9, 27, 81, 243
148 : 1, 2, 4, 37, 74, 148
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,491,216,243,148, is 1.
Now, the common factors can be found like this.
398:2x 199
491:491
216:2x 2x 2x 3x 3x 3
243:3x 3x 3x 3x 3
148:2x 2x 37
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 1518050797632/(1x216)
LCM = 1518050797632/216
LCM = 7028012952
Thus, we can understand that the LCM of 398,491,216,243,148 is 7028012952.
