Find LCM of 403,408,966,939,748 with Prime Factorization
| 2 | 403, 408, 966, 939, 748 |
| 2 | 403, 204, 483, 939, 374 |
| 3 | 403, 102, 483, 939, 187 |
| 17 | 403, 34, 161, 313, 187 |
| 403, 2, 161, 313, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 403 x 2 x 161 x 313 x 11 = 91144004952
Therefore, the lowest common multiple of 403,408,966,939,748 is 91144004952.
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.
403 x 408 x 966 x 939 x 748 = 111560262061248
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.
403 : 1, 13, 31, 403
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
939 : 1, 3, 313, 939
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 403,408,966,939,748, is 1.
Now, the common factors can be found like this.
403:13x 31
408:2x 2x 2x 3x 17
966:2x 3x 7x 23
939:3x 313
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.
2x 2x 2x 3x 3x 17 = 1224
Therefore, the value for common factors is 1224.
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 = 111560262061248/(1x1224)
LCM = 111560262061248/1224
LCM = 91144004952
Thus, we can understand that the LCM of 403,408,966,939,748 is 91144004952.
