Given numbers are 762,544,138,649,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,544,138,649,724 is 559983180768.
Find LCM of 762,544,138,649,724 with Prime Factorization
| 2 | 762, 544, 138, 649, 724 |
| 2 | 381, 272, 69, 649, 362 |
| 3 | 381, 136, 69, 649, 181 |
| 127, 136, 23, 649, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 127 x 136 x 23 x 649 x 181 = 559983180768
Therefore, the lowest common multiple of 762,544,138,649,724 is 559983180768.
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.
762 x 544 x 138 x 649 x 724 = 26879192676864
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
138 : 1, 2, 3, 6, 23, 46, 69, 138
649 : 1, 11, 59, 649
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,544,138,649,724, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
544:2x 2x 2x 2x 2x 17
138:2x 3x 23
649:11x 59
724:2x 2x 181
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 26879192676864/(1x48)
LCM = 26879192676864/48
LCM = 559983180768
Thus, we can understand that the LCM of 762,544,138,649,724 is 559983180768.
