Given numbers are 426,205,741
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,205,741 is 21570510.
Find LCM of 426,205,741 with Prime Factorization
| 3 | 426, 205, 741 |
| 142, 205, 247 |
Multiply the prime numbers at the bottom and the left side.
3 x 142 x 205 x 247 = 21570510
Therefore, the lowest common multiple of 426,205,741 is 21570510.
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.
426 x 205 x 741 = 64711530
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
205 : 1, 5, 41, 205
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,205,741, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
205:5x 41
741:3x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 64711530/(1x3)
LCM = 64711530/3
LCM = 21570510
Thus, we can understand that the LCM of 426,205,741 is 21570510.
