Given numbers are 892,551,892,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 892,551,892,438 is 107636748.
Find LCM of 892,551,892,438 with Prime Factorization
| 2 | 892, 551, 892, 438 |
| 2 | 446, 551, 446, 219 |
| 223 | 223, 551, 223, 219 |
| 1, 551, 1, 219 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 223 x 1 x 551 x 1 x 219 = 107636748
Therefore, the lowest common multiple of 892,551,892,438 is 107636748.
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.
892 x 551 x 892 x 438 = 192023958432
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.
892 : 1, 2, 4, 223, 446, 892
551 : 1, 19, 29, 551
892 : 1, 2, 4, 223, 446, 892
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,551,892,438, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
551:19x 29
892:2x 2x 223
438:2x 3x 73
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 223 = 1784
Therefore, the value for common factors is 1784.
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 = 192023958432/(1x1784)
LCM = 192023958432/1784
LCM = 107636748
Thus, we can understand that the LCM of 892,551,892,438 is 107636748.
