Given numbers are 785,349,720,785,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,349,720,785,291 is 3826743120.
Find LCM of 785,349,720,785,291 with Prime Factorization
| 3 | 785, 349, 720, 785, 291 |
| 5 | 785, 349, 240, 785, 97 |
| 157 | 157, 349, 48, 157, 97 |
| 1, 349, 48, 1, 97 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 157 x 1 x 349 x 48 x 1 x 97 = 3826743120
Therefore, the lowest common multiple of 785,349,720,785,291 is 3826743120.
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 349 x 720 x 785 x 291 = 45059900238000
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
349 : 1, 349
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
785 : 1, 5, 157, 785
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,349,720,785,291, is 1.
Now, the common factors can be found like this.
785:5x 157
349:349
720:2x 2x 2x 2x 3x 3x 5
785:5x 157
291:3x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 157 = 11775
Therefore, the value for common factors is 11775.
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 = 45059900238000/(1x11775)
LCM = 45059900238000/11775
LCM = 3826743120
Thus, we can understand that the LCM of 785,349,720,785,291 is 3826743120.
