Given numbers are 684,802,961,133
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,802,961,133 is 1845108468.
Find LCM of 684,802,961,133 with Prime Factorization
| 2 | 684, 802, 961, 133 |
| 19 | 342, 401, 961, 133 |
| 18, 401, 961, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 18 x 401 x 961 x 7 = 1845108468
Therefore, the lowest common multiple of 684,802,961,133 is 1845108468.
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.
684 x 802 x 961 x 133 = 70114121784
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
802 : 1, 2, 401, 802
961 : 1, 31, 961
133 : 1, 7, 19, 133
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,802,961,133, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
802:2x 401
961:31x 31
133:7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 70114121784/(1x38)
LCM = 70114121784/38
LCM = 1845108468
Thus, we can understand that the LCM of 684,802,961,133 is 1845108468.
