The LCM of 748,121,949,646,147 is 21808782996.
Find LCM of 748,121,949,646,147 with Prime Factorization
| 2 | 748, 121, 949, 646, 147 |
| 11 | 374, 121, 949, 323, 147 |
| 17 | 34, 11, 949, 323, 147 |
| 2, 11, 949, 19, 147 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 2 x 11 x 949 x 19 x 147 = 21808782996
Therefore, the lowest common multiple of 748,121,949,646,147 is 21808782996.
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.
748 x 121 x 949 x 646 x 147 = 8156484840504
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
121 : 1, 11, 121
949 : 1, 13, 73, 949
646 : 1, 2, 17, 19, 34, 38, 323, 646
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,121,949,646,147, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
121:11x 11
949:13x 73
646:2x 17x 19
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 8156484840504/(1x374)
LCM = 8156484840504/374
LCM = 21808782996
Thus, we can understand that the LCM of 748,121,949,646,147 is 21808782996.
