Find LCM of 572,436,786,309,390 with Prime Factorization
| 2 | 572, 436, 786, 309, 390 |
| 2 | 286, 218, 393, 309, 195 |
| 3 | 143, 109, 393, 309, 195 |
| 13 | 143, 109, 131, 103, 65 |
| 11, 109, 131, 103, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 11 x 109 x 131 x 103 x 5 = 12618923460
Therefore, the lowest common multiple of 572,436,786,309,390 is 12618923460.
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.
572 x 436 x 786 x 309 x 390 = 23622624717120
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
436 : 1, 2, 4, 109, 218, 436
786 : 1, 2, 3, 6, 131, 262, 393, 786
309 : 1, 3, 103, 309
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,436,786,309,390, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
436:2x 2x 109
786:2x 3x 131
309:3x 103
390:2x 3x 5x 13
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 13 = 1872
Therefore, the value for common factors is 1872.
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 = 23622624717120/(1x1872)
LCM = 23622624717120/1872
LCM = 12618923460
Thus, we can understand that the LCM of 572,436,786,309,390 is 12618923460.
