Find LCM of 398,372,251,728,546 with Prime Factorization
| 2 | 398, 372, 251, 728, 546 |
| 2 | 199, 186, 251, 364, 273 |
| 3 | 199, 93, 251, 182, 273 |
| 7 | 199, 31, 251, 182, 91 |
| 13 | 199, 31, 251, 26, 13 |
| 199, 31, 251, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 199 x 31 x 251 x 2 x 1 = 3381747096
Therefore, the lowest common multiple of 398,372,251,728,546 is 3381747096.
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 372 x 251 x 728 x 546 = 14771471315328
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
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
251 : 1, 251
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,372,251,728,546, is 1.
Now, the common factors can be found like this.
398:2x 199
372:2x 2x 3x 31
251:251
728:2x 2x 2x 7x 13
546:2x 3x 7x 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 2x 2x 2x 3x 7x 13 = 4368
Therefore, the value for common factors is 4368.
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 = 14771471315328/(1x4368)
LCM = 14771471315328/4368
LCM = 3381747096
Thus, we can understand that the LCM of 398,372,251,728,546 is 3381747096.
