Given numbers are 279,128,394,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,128,394,856 is 752773248.
Find LCM of 279,128,394,856 with Prime Factorization
2 | 279, 128, 394, 856 |
2 | 279, 64, 197, 428 |
2 | 279, 32, 197, 214 |
279, 16, 197, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 279 x 16 x 197 x 107 = 752773248
Therefore, the lowest common multiple of 279,128,394,856 is 752773248.
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.
279 x 128 x 394 x 856 = 12044371968
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.
279 : 1, 3, 9, 31, 93, 279
128 : 1, 2, 4, 8, 16, 32, 64, 128
394 : 1, 2, 197, 394
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,128,394,856, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
128:2x 2x 2x 2x 2x 2x 2
394:2x 197
856:2x 2x 2x 107
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 = 12044371968/(1x16)
LCM = 12044371968/16
LCM = 752773248
Thus, we can understand that the LCM of 279,128,394,856 is 752773248.
