Given numbers are 812,548,436,262,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,548,436,262,786 is 4765359228.
Find LCM of 812,548,436,262,786 with Prime Factorization
| 2 | 812, 548, 436, 262, 786 |
| 2 | 406, 274, 218, 131, 393 |
| 131 | 203, 137, 109, 131, 393 |
| 203, 137, 109, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 131 x 203 x 137 x 109 x 1 x 3 = 4765359228
Therefore, the lowest common multiple of 812,548,436,262,786 is 4765359228.
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.
812 x 548 x 436 x 262 x 786 = 39952771767552
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
548 : 1, 2, 4, 137, 274, 548
436 : 1, 2, 4, 109, 218, 436
262 : 1, 2, 131, 262
786 : 1, 2, 3, 6, 131, 262, 393, 786
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,548,436,262,786, is 2.
Now, the common factors can be found like this.
812:2x 2x 7x 29
548:2x 2x 137
436:2x 2x 109
262:2x 131
786:2x 3x 131
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 131 = 4192
Therefore, the value for common factors is 4192.
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 = 39952771767552/(2x4192)
LCM = 39952771767552/8384
LCM = 4765359228
Thus, we can understand that the LCM of 812,548,436,262,786 is 4765359228.
