Given numbers are 396,821,504,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,821,504,507 is 769224456.
Find LCM of 396,821,504,507 with Prime Factorization
| 2 | 396, 821, 504, 507 |
| 2 | 198, 821, 252, 507 |
| 3 | 99, 821, 126, 507 |
| 3 | 33, 821, 42, 169 |
| 11, 821, 14, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 821 x 14 x 169 = 769224456
Therefore, the lowest common multiple of 396,821,504,507 is 769224456.
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.
396 x 821 x 504 x 507 = 83076241248
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
821 : 1, 821
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,821,504,507, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
821:821
504:2x 2x 2x 3x 3x 7
507:3x 13x 13
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 3 = 108
Therefore, the value for common factors is 108.
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 = 83076241248/(1x108)
LCM = 83076241248/108
LCM = 769224456
Thus, we can understand that the LCM of 396,821,504,507 is 769224456.
