Given numbers are 785,471,470,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,471,470,756 is 27892620.
Find LCM of 785,471,470,756 with Prime Factorization
| 2 | 785, 471, 470, 756 |
| 3 | 785, 471, 235, 378 |
| 5 | 785, 157, 235, 126 |
| 157 | 157, 157, 47, 126 |
| 1, 1, 47, 126 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 157 x 1 x 1 x 47 x 126 = 27892620
Therefore, the lowest common multiple of 785,471,470,756 is 27892620.
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.
785 x 471 x 470 x 756 = 131374240200
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.
785 : 1, 5, 157, 785
471 : 1, 3, 157, 471
470 : 1, 2, 5, 10, 47, 94, 235, 470
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,471,470,756, is 1.
Now, the common factors can be found like this.
785:5x 157
471:3x 157
470:2x 5x 47
756:2x 2x 3x 3x 3x 7
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 5x 157 = 4710
Therefore, the value for common factors is 4710.
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 = 131374240200/(1x4710)
LCM = 131374240200/4710
LCM = 27892620
Thus, we can understand that the LCM of 785,471,470,756 is 27892620.
