Given numbers are 785,767,728,225,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,767,728,225,287 is 62208455400.
Find LCM of 785,767,728,225,287 with Prime Factorization
| 5 | 785, 767, 728, 225, 287 |
| 7 | 157, 767, 728, 45, 287 |
| 13 | 157, 767, 104, 45, 41 |
| 157, 59, 8, 45, 41 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 157 x 59 x 8 x 45 x 41 = 62208455400
Therefore, the lowest common multiple of 785,767,728,225,287 is 62208455400.
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 767 x 728 x 225 x 287 = 28304847207000
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
767 : 1, 13, 59, 767
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,767,728,225,287, is 1.
Now, the common factors can be found like this.
785:5x 157
767:13x 59
728:2x 2x 2x 7x 13
225:3x 3x 5x 5
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 13 = 455
Therefore, the value for common factors is 455.
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 = 28304847207000/(1x455)
LCM = 28304847207000/455
LCM = 62208455400
Thus, we can understand that the LCM of 785,767,728,225,287 is 62208455400.
