Given numbers are 760,686,176,398,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,686,176,398,170 is 19401369680.
Find LCM of 760,686,176,398,170 with Prime Factorization
| 2 | 760, 686, 176, 398, 170 |
| 2 | 380, 343, 88, 199, 85 |
| 2 | 190, 343, 44, 199, 85 |
| 5 | 95, 343, 22, 199, 85 |
| 19, 343, 22, 199, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 343 x 22 x 199 x 17 = 19401369680
Therefore, the lowest common multiple of 760,686,176,398,170 is 19401369680.
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.
760 x 686 x 176 x 398 x 170 = 6208438297600
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
686 : 1, 2, 7, 14, 49, 98, 343, 686
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
398 : 1, 2, 199, 398
170 : 1, 2, 5, 10, 17, 34, 85, 170
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,686,176,398,170, is 2.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
686:2x 7x 7x 7
176:2x 2x 2x 2x 11
398:2x 199
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 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 6208438297600/(2x160)
LCM = 6208438297600/320
LCM = 19401369680
Thus, we can understand that the LCM of 760,686,176,398,170 is 19401369680.
