Given numbers are 841,450,154,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 841,450,154,162 is 262265850.
Find LCM of 841,450,154,162 with Prime Factorization
| 2 | 841, 450, 154, 162 |
| 3 | 841, 225, 77, 81 |
| 3 | 841, 75, 77, 27 |
| 841, 25, 77, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 841 x 25 x 77 x 9 = 262265850
Therefore, the lowest common multiple of 841,450,154,162 is 262265850.
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.
841 x 450 x 154 x 162 = 9441570600
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.
841 : 1, 29, 841
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
154 : 1, 2, 7, 11, 14, 22, 77, 154
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 841,450,154,162, is 1.
Now, the common factors can be found like this.
841:29x 29
450:2x 3x 3x 5x 5
154:2x 7x 11
162:2x 3x 3x 3x 3
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 9441570600/(1x36)
LCM = 9441570600/36
LCM = 262265850
Thus, we can understand that the LCM of 841,450,154,162 is 262265850.
