Given numbers are 253,888,346,128
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,888,346,128 is 621869952.
Find LCM of 253,888,346,128 with Prime Factorization
| 2 | 253, 888, 346, 128 |
| 2 | 253, 444, 173, 64 |
| 2 | 253, 222, 173, 32 |
| 253, 111, 173, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 253 x 111 x 173 x 16 = 621869952
Therefore, the lowest common multiple of 253,888,346,128 is 621869952.
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.
253 x 888 x 346 x 128 = 9949919232
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.
253 : 1, 11, 23, 253
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
346 : 1, 2, 173, 346
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,888,346,128, is 1.
Now, the common factors can be found like this.
253:11x 23
888:2x 2x 2x 3x 37
346:2x 173
128:2x 2x 2x 2x 2x 2x 2
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 = 9949919232/(1x16)
LCM = 9949919232/16
LCM = 621869952
Thus, we can understand that the LCM of 253,888,346,128 is 621869952.
