Find LCM of 398,836,144,968,272 with Prime Factorization
| 2 | 398, 836, 144, 968, 272 |
| 2 | 199, 418, 72, 484, 136 |
| 2 | 199, 209, 36, 242, 68 |
| 2 | 199, 209, 18, 121, 34 |
| 11 | 199, 209, 9, 121, 17 |
| 199, 19, 9, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 199 x 19 x 9 x 11 x 17 = 1119962448
Therefore, the lowest common multiple of 398,836,144,968,272 is 1119962448.
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 836 x 144 x 968 x 272 = 12615257014272
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
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,836,144,968,272, is 2.
Now, the common factors can be found like this.
398:2x 199
836:2x 2x 11x 19
144:2x 2x 2x 2x 3x 3
968:2x 2x 2x 11x 11
272:2x 2x 2x 2x 17
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 2x 2x 2x 2x 2x 11 = 5632
Therefore, the value for common factors is 5632.
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 = 12615257014272/(2x5632)
LCM = 12615257014272/11264
LCM = 1119962448
Thus, we can understand that the LCM of 398,836,144,968,272 is 1119962448.
