The LCM of 367,472,408,646 is 167854056.
Find LCM of 367,472,408,646 with Prime Factorization
| 2 | 367, 472, 408, 646 |
| 2 | 367, 236, 204, 323 |
| 2 | 367, 118, 102, 323 |
| 17 | 367, 59, 51, 323 |
| 367, 59, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 367 x 59 x 3 x 19 = 167854056
Therefore, the lowest common multiple of 367,472,408,646 is 167854056.
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.
367 x 472 x 408 x 646 = 45656303232
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.
367 : 1, 367
472 : 1, 2, 4, 8, 59, 118, 236, 472
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 367,472,408,646, is 1.
Now, the common factors can be found like this.
367:367
472:2x 2x 2x 59
408:2x 2x 2x 3x 17
646:2x 17x 19
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 17 = 272
Therefore, the value for common factors is 272.
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 = 45656303232/(1x272)
LCM = 45656303232/272
LCM = 167854056
Thus, we can understand that the LCM of 367,472,408,646 is 167854056.
