Find LCM of 371,396,721,126 with Prime Factorization
| 2 | 371, 396, 721, 126 |
| 3 | 371, 198, 721, 63 |
| 3 | 371, 66, 721, 21 |
| 7 | 371, 22, 721, 7 |
| 53, 22, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 53 x 22 x 103 x 1 = 15132348
Therefore, the lowest common multiple of 371,396,721,126 is 15132348.
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.
371 x 396 x 721 x 126 = 13346730936
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.
371 : 1, 7, 53, 371
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
721 : 1, 7, 103, 721
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,396,721,126, is 1.
Now, the common factors can be found like this.
371:7x 53
396:2x 2x 3x 3x 11
721:7x 103
126:2x 3x 3x 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 3x 3x 7x 7 = 882
Therefore, the value for common factors is 882.
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 = 13346730936/(1x882)
LCM = 13346730936/882
LCM = 15132348
Thus, we can understand that the LCM of 371,396,721,126 is 15132348.
