Given numbers are 843,450,321,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,450,321,650 is 175891950.
Find LCM of 843,450,321,650 with Prime Factorization
| 2 | 843, 450, 321, 650 |
| 3 | 843, 225, 321, 325 |
| 5 | 281, 75, 107, 325 |
| 5 | 281, 15, 107, 65 |
| 281, 3, 107, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 281 x 3 x 107 x 13 = 175891950
Therefore, the lowest common multiple of 843,450,321,650 is 175891950.
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.
843 x 450 x 321 x 650 = 79151377500
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.
843 : 1, 3, 281, 843
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
321 : 1, 3, 107, 321
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,450,321,650, is 1.
Now, the common factors can be found like this.
843:3x 281
450:2x 3x 3x 5x 5
321:3x 107
650:2x 5x 5x 13
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 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 79151377500/(1x450)
LCM = 79151377500/450
LCM = 175891950
Thus, we can understand that the LCM of 843,450,321,650 is 175891950.
