Given numbers are 146,120,849,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 146,120,849,140 is 17353560.
Find LCM of 146,120,849,140 with Prime Factorization
| 2 | 146, 120, 849, 140 |
| 2 | 73, 60, 849, 70 |
| 3 | 73, 30, 849, 35 |
| 5 | 73, 10, 283, 35 |
| 73, 2, 283, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 73 x 2 x 283 x 7 = 17353560
Therefore, the lowest common multiple of 146,120,849,140 is 17353560.
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.
146 x 120 x 849 x 140 = 2082427200
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.
146 : 1, 2, 73, 146
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
849 : 1, 3, 283, 849
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 146,120,849,140, is 1.
Now, the common factors can be found like this.
146:2x 73
120:2x 2x 2x 3x 5
849:3x 283
140:2x 2x 5x 7
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 2082427200/(1x120)
LCM = 2082427200/120
LCM = 17353560
Thus, we can understand that the LCM of 146,120,849,140 is 17353560.
