Find LCM of 621,378,428,236 with Prime Factorization
| 2 | 621, 378, 428, 236 |
| 2 | 621, 189, 214, 118 |
| 3 | 621, 189, 107, 59 |
| 3 | 207, 63, 107, 59 |
| 3 | 69, 21, 107, 59 |
| 23, 7, 107, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 23 x 7 x 107 x 59 = 109770444
Therefore, the lowest common multiple of 621,378,428,236 is 109770444.
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.
621 x 378 x 428 x 236 = 23710415904
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
428 : 1, 2, 4, 107, 214, 428
236 : 1, 2, 4, 59, 118, 236
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,378,428,236, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
378:2x 3x 3x 3x 7
428:2x 2x 107
236:2x 2x 59
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 23710415904/(1x216)
LCM = 23710415904/216
LCM = 109770444
Thus, we can understand that the LCM of 621,378,428,236 is 109770444.
