Given numbers are 785,409,395,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,409,395,637 is 16156953995.
Find LCM of 785,409,395,637 with Prime Factorization
| 5 | 785, 409, 395, 637 |
| 157, 409, 79, 637 |
Multiply the prime numbers at the bottom and the left side.
5 x 157 x 409 x 79 x 637 = 16156953995
Therefore, the lowest common multiple of 785,409,395,637 is 16156953995.
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 409 x 395 x 637 = 80784769975
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
409 : 1, 409
395 : 1, 5, 79, 395
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,409,395,637, is 1.
Now, the common factors can be found like this.
785:5x 157
409:409
395:5x 79
637:7x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 80784769975/(1x5)
LCM = 80784769975/5
LCM = 16156953995
Thus, we can understand that the LCM of 785,409,395,637 is 16156953995.
