Given numbers are 630,405,403,551
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,405,403,551 is 1259040510.
Find LCM of 630,405,403,551 with Prime Factorization
3 | 630, 405, 403, 551 |
3 | 210, 135, 403, 551 |
5 | 70, 45, 403, 551 |
14, 9, 403, 551 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 14 x 9 x 403 x 551 = 1259040510
Therefore, the lowest common multiple of 630,405,403,551 is 1259040510.
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.
630 x 405 x 403 x 551 = 56656822950
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
403 : 1, 13, 31, 403
551 : 1, 19, 29, 551
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,405,403,551, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
405:3x 3x 3x 3x 5
403:13x 31
551:19x 29
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 5 = 45
Therefore, the value for common factors is 45.
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 = 56656822950/(1x45)
LCM = 56656822950/45
LCM = 1259040510
Thus, we can understand that the LCM of 630,405,403,551 is 1259040510.
