Given numbers are 940,648,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 940,648,749 is 114057720.
Find LCM of 940,648,749 with Prime Factorization
| 2 | 940, 648, 749 |
| 2 | 470, 324, 749 |
| 235, 162, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 235 x 162 x 749 = 114057720
Therefore, the lowest common multiple of 940,648,749 is 114057720.
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.
940 x 648 x 749 = 456230880
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.
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,648,749, is 1.
Now, the common factors can be found like this.
940:2x 2x 5x 47
648:2x 2x 2x 3x 3x 3x 3
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 456230880/(1x4)
LCM = 456230880/4
LCM = 114057720
Thus, we can understand that the LCM of 940,648,749 is 114057720.
