Given numbers are 894,321,270,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 894,321,270,905 is 779134410.
Find LCM of 894,321,270,905 with Prime Factorization
| 2 | 894, 321, 270, 905 |
| 3 | 447, 321, 135, 905 |
| 5 | 149, 107, 45, 905 |
| 149, 107, 9, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 149 x 107 x 9 x 181 = 779134410
Therefore, the lowest common multiple of 894,321,270,905 is 779134410.
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 321 x 270 x 905 = 70122096900
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
321 : 1, 3, 107, 321
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,321,270,905, is 1.
Now, the common factors can be found like this.
894:2x 3x 149
321:3x 107
270:2x 3x 3x 3x 5
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 70122096900/(1x90)
LCM = 70122096900/90
LCM = 779134410
Thus, we can understand that the LCM of 894,321,270,905 is 779134410.
