Given numbers are 630,655,403,435,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,655,403,435,981 is 105133563990.
Find LCM of 630,655,403,435,981 with Prime Factorization
| 3 | 630, 655, 403, 435, 981 |
| 3 | 210, 655, 403, 145, 327 |
| 5 | 70, 655, 403, 145, 109 |
| 14, 131, 403, 29, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 14 x 131 x 403 x 29 x 109 = 105133563990
Therefore, the lowest common multiple of 630,655,403,435,981 is 105133563990.
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 655 x 403 x 435 x 981 = 70965155693250
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
655 : 1, 5, 131, 655
403 : 1, 13, 31, 403
435 : 1, 3, 5, 15, 29, 87, 145, 435
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,655,403,435,981, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
655:5x 131
403:13x 31
435:3x 5x 29
981:3x 3x 109
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 5x 5 = 675
Therefore, the value for common factors is 675.
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 = 70965155693250/(1x675)
LCM = 70965155693250/675
LCM = 105133563990
Thus, we can understand that the LCM of 630,655,403,435,981 is 105133563990.
