Find LCM of 972,313,776,162,428 with Prime Factorization
| 2 | 972, 313, 776, 162, 428 |
| 2 | 486, 313, 388, 81, 214 |
| 3 | 243, 313, 194, 81, 107 |
| 3 | 27, 313, 194, 81, 107 |
| 3 | 9, 313, 194, 27, 107 |
| 3 | 3, 313, 194, 9, 107 |
| 1, 313, 194, 3, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 1 x 313 x 194 x 3 x 107 = 6315330888
Therefore, the lowest common multiple of 972,313,776,162,428 is 6315330888.
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.
972 x 313 x 776 x 162 x 428 = 16369337661696
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
313 : 1, 313
776 : 1, 2, 4, 8, 97, 194, 388, 776
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,313,776,162,428, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
313:313
776:2x 2x 2x 97
162:2x 3x 3x 3x 3
428:2x 2x 107
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 2x 3x 3x 3x 3 = 2592
Therefore, the value for common factors is 2592.
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 = 16369337661696/(1x2592)
LCM = 16369337661696/2592
LCM = 6315330888
Thus, we can understand that the LCM of 972,313,776,162,428 is 6315330888.
