Given numbers are 455,637,663,699
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,637,663,699 is 37847355.
Find LCM of 455,637,663,699 with Prime Factorization
| 3 | 455, 637, 663, 699 |
| 7 | 455, 637, 221, 233 |
| 13 | 65, 91, 221, 233 |
| 5, 7, 17, 233 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 5 x 7 x 17 x 233 = 37847355
Therefore, the lowest common multiple of 455,637,663,699 is 37847355.
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.
455 x 637 x 663 x 699 = 134320262895
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
637 : 1, 7, 13, 49, 91, 637
663 : 1, 3, 13, 17, 39, 51, 221, 663
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,637,663,699, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
637:7x 7x 13
663:3x 13x 17
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 13x 13 = 3549
Therefore, the value for common factors is 3549.
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 = 134320262895/(1x3549)
LCM = 134320262895/3549
LCM = 37847355
Thus, we can understand that the LCM of 455,637,663,699 is 37847355.
