The LCM of 154,398,716,665,895 is 1042270460.
Find LCM of 154,398,716,665,895 with Prime Factorization
| 2 | 154, 398, 716, 665, 895 |
| 5 | 77, 199, 358, 665, 895 |
| 7 | 77, 199, 358, 133, 179 |
| 179 | 11, 199, 358, 19, 179 |
| 11, 199, 2, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 179 x 11 x 199 x 2 x 19 x 1 = 1042270460
Therefore, the lowest common multiple of 154,398,716,665,895 is 1042270460.
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.
154 x 398 x 716 x 665 x 895 = 26119297727600
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
398 : 1, 2, 199, 398
716 : 1, 2, 4, 179, 358, 716
665 : 1, 5, 7, 19, 35, 95, 133, 665
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,398,716,665,895, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
398:2x 199
716:2x 2x 179
665:5x 7x 19
895:5x 179
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 7x 179 = 25060
Therefore, the value for common factors is 25060.
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 = 26119297727600/(1x25060)
LCM = 26119297727600/25060
LCM = 1042270460
Thus, we can understand that the LCM of 154,398,716,665,895 is 1042270460.
