Given numbers are 747,961,253,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,961,253,165 is 908101755.
Find LCM of 747,961,253,165 with Prime Factorization
| 3 | 747, 961, 253, 165 |
| 11 | 249, 961, 253, 55 |
| 249, 961, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 249 x 961 x 23 x 5 = 908101755
Therefore, the lowest common multiple of 747,961,253,165 is 908101755.
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.
747 x 961 x 253 x 165 = 29967357915
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.
747 : 1, 3, 9, 83, 249, 747
961 : 1, 31, 961
253 : 1, 11, 23, 253
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,961,253,165, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
961:31x 31
253:11x 23
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 29967357915/(1x33)
LCM = 29967357915/33
LCM = 908101755
Thus, we can understand that the LCM of 747,961,253,165 is 908101755.
