Find LCM of 862,353,243,972 with Prime Factorization
| 2 | 862, 353, 243, 972 |
| 3 | 431, 353, 243, 486 |
| 3 | 431, 353, 81, 162 |
| 3 | 431, 353, 27, 54 |
| 3 | 431, 353, 9, 18 |
| 3 | 431, 353, 3, 6 |
| 431, 353, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 3 x 431 x 353 x 1 x 2 = 147882996
Therefore, the lowest common multiple of 862,353,243,972 is 147882996.
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.
862 x 353 x 243 x 972 = 71871136056
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.
862 : 1, 2, 431, 862
353 : 1, 353
243 : 1, 3, 9, 27, 81, 243
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,353,243,972, is 1.
Now, the common factors can be found like this.
862:2x 431
353:353
243:3x 3x 3x 3x 3
972:2x 2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 71871136056/(1x486)
LCM = 71871136056/486
LCM = 147882996
Thus, we can understand that the LCM of 862,353,243,972 is 147882996.
