Given numbers are 256,921,506,773,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,921,506,773,474 is 3642727646976.
Find LCM of 256,921,506,773,474 with Prime Factorization
| 2 | 256, 921, 506, 773, 474 |
| 3 | 128, 921, 253, 773, 237 |
| 128, 307, 253, 773, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 128 x 307 x 253 x 773 x 79 = 3642727646976
Therefore, the lowest common multiple of 256,921,506,773,474 is 3642727646976.
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 921 x 506 x 773 x 474 = 43712731763712
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
921 : 1, 3, 307, 921
506 : 1, 2, 11, 22, 23, 46, 253, 506
773 : 1, 773
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,921,506,773,474, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
921:3x 307
506:2x 11x 23
773:773
474:2x 3x 79
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 3 = 12
Therefore, the value for common factors is 12.
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 = 43712731763712/(1x12)
LCM = 43712731763712/12
LCM = 3642727646976
Thus, we can understand that the LCM of 256,921,506,773,474 is 3642727646976.
