Given numbers are 903,957,403,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 903,957,403,748 is 7893914028.
Find LCM of 903,957,403,748 with Prime Factorization
| 3 | 903, 957, 403, 748 |
| 11 | 301, 319, 403, 748 |
| 301, 29, 403, 68 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 301 x 29 x 403 x 68 = 7893914028
Therefore, the lowest common multiple of 903,957,403,748 is 7893914028.
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.
903 x 957 x 403 x 748 = 260499162924
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
957 : 1, 3, 11, 29, 33, 87, 319, 957
403 : 1, 13, 31, 403
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,957,403,748, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
957:3x 11x 29
403:13x 31
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 260499162924/(1x33)
LCM = 260499162924/33
LCM = 7893914028
Thus, we can understand that the LCM of 903,957,403,748 is 7893914028.
