Find LCM of 256,179,578,438,392 with Prime Factorization
2 | 256, 179, 578, 438, 392 |
2 | 128, 179, 289, 219, 196 |
2 | 64, 179, 289, 219, 98 |
32, 179, 289, 219, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 32 x 179 x 289 x 219 x 49 = 142112092416
Therefore, the lowest common multiple of 256,179,578,438,392 is 142112092416.
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.
256 x 179 x 578 x 438 x 392 = 4547586957312
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
179 : 1, 179
578 : 1, 2, 17, 34, 289, 578
438 : 1, 2, 3, 6, 73, 146, 219, 438
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,179,578,438,392, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
179:179
578:2x 17x 17
438:2x 3x 73
392:2x 2x 2x 7x 7
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 2 = 32
Therefore, the value for common factors is 32.
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 = 4547586957312/(1x32)
LCM = 4547586957312/32
LCM = 142112092416
Thus, we can understand that the LCM of 256,179,578,438,392 is 142112092416.
