Given numbers are 646,792,671,762,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,792,671,762,743 is 1472482268136.
Find LCM of 646,792,671,762,743 with Prime Factorization
| 2 | 646, 792, 671, 762, 743 |
| 3 | 323, 396, 671, 381, 743 |
| 11 | 323, 132, 671, 127, 743 |
| 323, 12, 61, 127, 743 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 323 x 12 x 61 x 127 x 743 = 1472482268136
Therefore, the lowest common multiple of 646,792,671,762,743 is 1472482268136.
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.
646 x 792 x 671 x 762 x 743 = 194367659393952
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
671 : 1, 11, 61, 671
762 : 1, 2, 3, 6, 127, 254, 381, 762
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,792,671,762,743, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
792:2x 2x 2x 3x 3x 11
671:11x 61
762:2x 3x 127
743:743
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 194367659393952/(1x132)
LCM = 194367659393952/132
LCM = 1472482268136
Thus, we can understand that the LCM of 646,792,671,762,743 is 1472482268136.
