Given numbers are 762,646,871,605,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,646,871,605,351 is 1167275936970.
Find LCM of 762,646,871,605,351 with Prime Factorization
| 2 | 762, 646, 871, 605, 351 |
| 3 | 381, 323, 871, 605, 351 |
| 13 | 127, 323, 871, 605, 117 |
| 127, 323, 67, 605, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 127 x 323 x 67 x 605 x 9 = 1167275936970
Therefore, the lowest common multiple of 762,646,871,605,351 is 1167275936970.
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 646 x 871 x 605 x 351 = 91047523083660
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
871 : 1, 13, 67, 871
605 : 1, 5, 11, 55, 121, 605
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,646,871,605,351, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
646:2x 17x 19
871:13x 67
605:5x 11x 11
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 91047523083660/(1x78)
LCM = 91047523083660/78
LCM = 1167275936970
Thus, we can understand that the LCM of 762,646,871,605,351 is 1167275936970.
