Given numbers are 462,578,990,692
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,578,990,692 is 692958420.
Find LCM of 462,578,990,692 with Prime Factorization
| 2 | 462, 578, 990, 692 |
| 3 | 231, 289, 495, 346 |
| 11 | 77, 289, 165, 346 |
| 7, 289, 15, 346 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 7 x 289 x 15 x 346 = 692958420
Therefore, the lowest common multiple of 462,578,990,692 is 692958420.
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.
462 x 578 x 990 x 692 = 182941022880
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
578 : 1, 2, 17, 34, 289, 578
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
692 : 1, 2, 4, 173, 346, 692
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,578,990,692, is 2.
Now, the common factors can be found like this.
462:2x 3x 7x 11
578:2x 17x 17
990:2x 3x 3x 5x 11
692:2x 2x 173
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 182941022880/(2x132)
LCM = 182941022880/264
LCM = 692958420
Thus, we can understand that the LCM of 462,578,990,692 is 692958420.
