Given numbers are 297,689,712,802,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 297,689,712,802,992 is 7244721959904.
Find LCM of 297,689,712,802,992 with Prime Factorization
| 2 | 297, 689, 712, 802, 992 |
| 2 | 297, 689, 356, 401, 496 |
| 2 | 297, 689, 178, 401, 248 |
| 297, 689, 89, 401, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 297 x 689 x 89 x 401 x 124 = 7244721959904
Therefore, the lowest common multiple of 297,689,712,802,992 is 7244721959904.
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.
297 x 689 x 712 x 802 x 992 = 115915551358464
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.
297 : 1, 3, 9, 11, 27, 33, 99, 297
689 : 1, 13, 53, 689
712 : 1, 2, 4, 8, 89, 178, 356, 712
802 : 1, 2, 401, 802
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,689,712,802,992, is 1.
Now, the common factors can be found like this.
297:3x 3x 3x 11
689:13x 53
712:2x 2x 2x 89
802:2x 401
992:2x 2x 2x 2x 2x 31
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 115915551358464/(1x16)
LCM = 115915551358464/16
LCM = 7244721959904
Thus, we can understand that the LCM of 297,689,712,802,992 is 7244721959904.
