Given numbers are 634,551,986,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,551,986,634 is 5938678.
Find LCM of 634,551,986,634 with Prime Factorization
| 2 | 634, 551, 986, 634 |
| 29 | 317, 551, 493, 317 |
| 317 | 317, 19, 17, 317 |
| 1, 19, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 317 x 1 x 19 x 17 x 1 = 5938678
Therefore, the lowest common multiple of 634,551,986,634 is 5938678.
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.
634 x 551 x 986 x 634 = 218377067416
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.
634 : 1, 2, 317, 634
551 : 1, 19, 29, 551
986 : 1, 2, 17, 29, 34, 58, 493, 986
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,551,986,634, is 1.
Now, the common factors can be found like this.
634:2x 317
551:19x 29
986:2x 17x 29
634:2x 317
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 29x 317 = 36772
Therefore, the value for common factors is 36772.
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 = 218377067416/(1x36772)
LCM = 218377067416/36772
LCM = 5938678
Thus, we can understand that the LCM of 634,551,986,634 is 5938678.
