Find LCM of 748,972,243,272 with Prime Factorization
| 2 | 748, 972, 243, 272 |
| 2 | 374, 486, 243, 136 |
| 3 | 187, 243, 243, 68 |
| 3 | 187, 81, 81, 68 |
| 3 | 187, 27, 27, 68 |
| 3 | 187, 9, 9, 68 |
| 3 | 187, 3, 3, 68 |
| 17 | 187, 1, 1, 68 |
| 11, 1, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 3 x 17 x 11 x 1 x 1 x 4 = 727056
Therefore, the lowest common multiple of 748,972,243,272 is 727056.
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 972 x 243 x 272 = 48055493376
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
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
243 : 1, 3, 9, 27, 81, 243
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,972,243,272, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
972:2x 2x 3x 3x 3x 3x 3
243:3x 3x 3x 3x 3
272:2x 2x 2x 2x 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 2x 3x 3x 3x 3x 3x 17 = 66096
Therefore, the value for common factors is 66096.
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 = 48055493376/(1x66096)
LCM = 48055493376/66096
LCM = 727056
Thus, we can understand that the LCM of 748,972,243,272 is 727056.
