Given numbers are 399,762,402,762,207
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,762,402,762,207 is 468522558.
Find LCM of 399,762,402,762,207 with Prime Factorization
| 2 | 399, 762, 402, 762, 207 |
| 3 | 399, 381, 201, 381, 207 |
| 127 | 133, 127, 67, 127, 69 |
| 133, 1, 67, 1, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 133 x 1 x 67 x 1 x 69 = 468522558
Therefore, the lowest common multiple of 399,762,402,762,207 is 468522558.
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.
399 x 762 x 402 x 762 x 207 = 19278766216584
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
762 : 1, 2, 3, 6, 127, 254, 381, 762
402 : 1, 2, 3, 6, 67, 134, 201, 402
762 : 1, 2, 3, 6, 127, 254, 381, 762
207 : 1, 3, 9, 23, 69, 207
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,762,402,762,207, is 3.
Now, the common factors can be found like this.
399:3x 7x 19
762:2x 3x 127
402:2x 3x 67
762:2x 3x 127
207:3x 3x 23
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 3x 3x 3x 127 = 13716
Therefore, the value for common factors is 13716.
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 = 19278766216584/(3x13716)
LCM = 19278766216584/41148
LCM = 468522558
Thus, we can understand that the LCM of 399,762,402,762,207 is 468522558.
