Given numbers are 262,471,785,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 262,471,785,742 is 228910710.
Find LCM of 262,471,785,742 with Prime Factorization
| 2 | 262, 471, 785, 742 |
| 157 | 131, 471, 785, 371 |
| 131, 3, 5, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 131 x 3 x 5 x 371 = 228910710
Therefore, the lowest common multiple of 262,471,785,742 is 228910710.
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.
262 x 471 x 785 x 742 = 71877962940
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.
262 : 1, 2, 131, 262
471 : 1, 3, 157, 471
785 : 1, 5, 157, 785
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,471,785,742, is 1.
Now, the common factors can be found like this.
262:2x 131
471:3x 157
785:5x 157
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 157 = 314
Therefore, the value for common factors is 314.
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 = 71877962940/(1x314)
LCM = 71877962940/314
LCM = 228910710
Thus, we can understand that the LCM of 262,471,785,742 is 228910710.
