Given numbers are 669,897,813,962
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,897,813,962 is 4011421674.
Find LCM of 669,897,813,962 with Prime Factorization
| 3 | 669, 897, 813, 962 |
| 13 | 223, 299, 271, 962 |
| 223, 23, 271, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 223 x 23 x 271 x 74 = 4011421674
Therefore, the lowest common multiple of 669,897,813,962 is 4011421674.
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.
669 x 897 x 813 x 962 = 469336335858
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.
669 : 1, 3, 223, 669
897 : 1, 3, 13, 23, 39, 69, 299, 897
813 : 1, 3, 271, 813
962 : 1, 2, 13, 26, 37, 74, 481, 962
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,897,813,962, is 1.
Now, the common factors can be found like this.
669:3x 223
897:3x 13x 23
813:3x 271
962:2x 13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 469336335858/(1x117)
LCM = 469336335858/117
LCM = 4011421674
Thus, we can understand that the LCM of 669,897,813,962 is 4011421674.
