Given numbers are 753,378,504,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,378,504,742 is 20114136.
Find LCM of 753,378,504,742 with Prime Factorization
| 2 | 753, 378, 504, 742 |
| 3 | 753, 189, 252, 371 |
| 3 | 251, 63, 84, 371 |
| 7 | 251, 21, 28, 371 |
| 251, 3, 4, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 251 x 3 x 4 x 53 = 20114136
Therefore, the lowest common multiple of 753,378,504,742 is 20114136.
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.
753 x 378 x 504 x 742 = 106444007712
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.
753 : 1, 3, 251, 753
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,378,504,742, is 1.
Now, the common factors can be found like this.
753:3x 251
378:2x 3x 3x 3x 7
504:2x 2x 2x 3x 3x 7
742:2x 7x 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 3x 3x 3x 7x 7 = 5292
Therefore, the value for common factors is 5292.
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 = 106444007712/(1x5292)
LCM = 106444007712/5292
LCM = 20114136
Thus, we can understand that the LCM of 753,378,504,742 is 20114136.
