Find LCM of 251,979,368,128,397 with Prime Factorization
2 | 251, 979, 368, 128, 397 |
2 | 251, 979, 184, 64, 397 |
2 | 251, 979, 92, 32, 397 |
2 | 251, 979, 46, 16, 397 |
251, 979, 23, 8, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 251 x 979 x 23 x 8 x 397 = 287200191872
Therefore, the lowest common multiple of 251,979,368,128,397 is 287200191872.
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.
251 x 979 x 368 x 128 x 397 = 4595203069952
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.
251 : 1, 251
979 : 1, 11, 89, 979
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
128 : 1, 2, 4, 8, 16, 32, 64, 128
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,979,368,128,397, is 1.
Now, the common factors can be found like this.
251:251
979:11x 89
368:2x 2x 2x 2x 23
128:2x 2x 2x 2x 2x 2x 2
397:397
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 2 = 16
Therefore, the value for common factors is 16.
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 = 4595203069952/(1x16)
LCM = 4595203069952/16
LCM = 287200191872
Thus, we can understand that the LCM of 251,979,368,128,397 is 287200191872.
