Given numbers are 635,637,556,217,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,637,556,217,693 is 690215706180.
Find LCM of 635,637,556,217,693 with Prime Factorization
| 7 | 635, 637, 556, 217, 693 |
| 635, 91, 556, 31, 99 |
Multiply the prime numbers at the bottom and the left side.
7 x 635 x 91 x 556 x 31 x 99 = 690215706180
Therefore, the lowest common multiple of 635,637,556,217,693 is 690215706180.
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.
635 x 637 x 556 x 217 x 693 = 33820569602820
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.
635 : 1, 5, 127, 635
637 : 1, 7, 13, 49, 91, 637
556 : 1, 2, 4, 139, 278, 556
217 : 1, 7, 31, 217
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,637,556,217,693, is 1.
Now, the common factors can be found like this.
635:5x 127
637:7x 7x 13
556:2x 2x 139
217:7x 31
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 33820569602820/(1x49)
LCM = 33820569602820/49
LCM = 690215706180
Thus, we can understand that the LCM of 635,637,556,217,693 is 690215706180.
