Given numbers are 294,840,939,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 294,840,939,749 is 196927080.
Find LCM of 294,840,939,749 with Prime Factorization
| 2 | 294, 840, 939, 749 |
| 3 | 147, 420, 939, 749 |
| 7 | 49, 140, 313, 749 |
| 7, 20, 313, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 20 x 313 x 107 = 196927080
Therefore, the lowest common multiple of 294,840,939,749 is 196927080.
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.
294 x 840 x 939 x 749 = 173689684560
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.
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
939 : 1, 3, 313, 939
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 294,840,939,749, is 1.
Now, the common factors can be found like this.
294:2x 3x 7x 7
840:2x 2x 2x 3x 5x 7
939:3x 313
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 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 173689684560/(1x882)
LCM = 173689684560/882
LCM = 196927080
Thus, we can understand that the LCM of 294,840,939,749 is 196927080.
