Given numbers are 747,726,310,781,122
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,726,310,781,122 is 121354490070.
Find LCM of 747,726,310,781,122 with Prime Factorization
| 2 | 747, 726, 310, 781, 122 |
| 3 | 747, 363, 155, 781, 61 |
| 11 | 249, 121, 155, 781, 61 |
| 249, 11, 155, 71, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 249 x 11 x 155 x 71 x 61 = 121354490070
Therefore, the lowest common multiple of 747,726,310,781,122 is 121354490070.
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 726 x 310 x 781 x 122 = 16018792689240
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
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
310 : 1, 2, 5, 10, 31, 62, 155, 310
781 : 1, 11, 71, 781
122 : 1, 2, 61, 122
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,726,310,781,122, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
726:2x 3x 11x 11
310:2x 5x 31
781:11x 71
122:2x 61
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 = 16018792689240/(1x132)
LCM = 16018792689240/132
LCM = 121354490070
Thus, we can understand that the LCM of 747,726,310,781,122 is 121354490070.
