Given numbers are 669,423,423,365
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,423,423,365 is 34430085.
Find LCM of 669,423,423,365 with Prime Factorization
| 3 | 669, 423, 423, 365 |
| 3 | 223, 141, 141, 365 |
| 47 | 223, 47, 47, 365 |
| 223, 1, 1, 365 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 47 x 223 x 1 x 1 x 365 = 34430085
Therefore, the lowest common multiple of 669,423,423,365 is 34430085.
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 423 x 423 x 365 = 43691777865
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
423 : 1, 3, 9, 47, 141, 423
423 : 1, 3, 9, 47, 141, 423
365 : 1, 5, 73, 365
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,423,423,365, is 1.
Now, the common factors can be found like this.
669:3x 223
423:3x 3x 47
423:3x 3x 47
365:5x 73
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 3x 47 = 1269
Therefore, the value for common factors is 1269.
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 = 43691777865/(1x1269)
LCM = 43691777865/1269
LCM = 34430085
Thus, we can understand that the LCM of 669,423,423,365 is 34430085.
