Given numbers are 812,692,464
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,692,464 is 561904.
Find LCM of 812,692,464 with Prime Factorization
| 2 | 812, 692, 464 |
| 2 | 406, 346, 232 |
| 29 | 203, 173, 116 |
| 7, 173, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 7 x 173 x 4 = 561904
Therefore, the lowest common multiple of 812,692,464 is 561904.
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 692 x 464 = 260723456
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
692 : 1, 2, 4, 173, 346, 692
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,692,464, is 4.
Now, the common factors can be found like this.
812:2x 2x 7x 29
692:2x 2x 173
464:2x 2x 2x 2x 29
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 29 = 116
Therefore, the value for common factors is 116.
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 = 260723456/(4x116)
LCM = 260723456/464
LCM = 561904
Thus, we can understand that the LCM of 812,692,464 is 561904.
