Given numbers are 894,121,421,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,121,421,605 is 227706270.
Find LCM of 894,121,421,605 with Prime Factorization
| 11 | 894, 121, 421, 605 |
| 11 | 894, 11, 421, 55 |
| 894, 1, 421, 5 |
Multiply the prime numbers at the bottom and the left side.
11 x 11 x 894 x 1 x 421 x 5 = 227706270
Therefore, the lowest common multiple of 894,121,421,605 is 227706270.
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.
894 x 121 x 421 x 605 = 27552458670
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
121 : 1, 11, 121
421 : 1, 421
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,121,421,605, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
121:11x 11
421:421
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 27552458670/(1x121)
LCM = 27552458670/121
LCM = 227706270
Thus, we can understand that the LCM of 894,121,421,605 is 227706270.
