Given numbers are 742,890,940,145,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,890,940,145,901 is 15301664980.
Find LCM of 742,890,940,145,901 with Prime Factorization
| 2 | 742, 890, 940, 145, 901 |
| 5 | 371, 445, 470, 145, 901 |
| 53 | 371, 89, 94, 29, 901 |
| 7, 89, 94, 29, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 53 x 7 x 89 x 94 x 29 x 17 = 15301664980
Therefore, the lowest common multiple of 742,890,940,145,901 is 15301664980.
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.
742 x 890 x 940 x 145 x 901 = 81098824394000
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
890 : 1, 2, 5, 10, 89, 178, 445, 890
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
145 : 1, 5, 29, 145
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,890,940,145,901, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
890:2x 5x 89
940:2x 2x 5x 47
145:5x 29
901:17x 53
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 5x 5x 53 = 5300
Therefore, the value for common factors is 5300.
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 = 81098824394000/(1x5300)
LCM = 81098824394000/5300
LCM = 15301664980
Thus, we can understand that the LCM of 742,890,940,145,901 is 15301664980.
