Given numbers are 895,142,680,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 895,142,680,170 is 8642120.
Find LCM of 895,142,680,170 with Prime Factorization
| 2 | 895, 142, 680, 170 |
| 5 | 895, 71, 340, 85 |
| 17 | 179, 71, 68, 17 |
| 179, 71, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 179 x 71 x 4 x 1 = 8642120
Therefore, the lowest common multiple of 895,142,680,170 is 8642120.
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.
895 x 142 x 680 x 170 = 14691604000
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.
895 : 1, 5, 179, 895
142 : 1, 2, 71, 142
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,142,680,170, is 1.
Now, the common factors can be found like this.
895:5x 179
142:2x 71
680:2x 2x 2x 5x 17
170:2x 5x 17
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 5x 5x 17 = 1700
Therefore, the value for common factors is 1700.
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 = 14691604000/(1x1700)
LCM = 14691604000/1700
LCM = 8642120
Thus, we can understand that the LCM of 895,142,680,170 is 8642120.
