The LCM of 976,398,396,854 is 134597232.
Find LCM of 976,398,396,854 with Prime Factorization
| 2 | 976, 398, 396, 854 |
| 2 | 488, 199, 198, 427 |
| 61 | 244, 199, 99, 427 |
| 4, 199, 99, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 61 x 4 x 199 x 99 x 7 = 134597232
Therefore, the lowest common multiple of 976,398,396,854 is 134597232.
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.
976 x 398 x 396 x 854 = 131366898432
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.
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
398 : 1, 2, 199, 398
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
854 : 1, 2, 7, 14, 61, 122, 427, 854
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,398,396,854, is 2.
Now, the common factors can be found like this.
976:2x 2x 2x 2x 61
398:2x 199
396:2x 2x 3x 3x 11
854:2x 7x 61
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 61 = 488
Therefore, the value for common factors is 488.
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 = 131366898432/(2x488)
LCM = 131366898432/976
LCM = 134597232
Thus, we can understand that the LCM of 976,398,396,854 is 134597232.
