Given numbers are 890,451,561,136
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,451,561,136 is 81883560.
Find LCM of 890,451,561,136 with Prime Factorization
| 2 | 890, 451, 561, 136 |
| 11 | 445, 451, 561, 68 |
| 17 | 445, 41, 51, 68 |
| 445, 41, 3, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 445 x 41 x 3 x 4 = 81883560
Therefore, the lowest common multiple of 890,451,561,136 is 81883560.
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.
890 x 451 x 561 x 136 = 30624451440
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
451 : 1, 11, 41, 451
561 : 1, 3, 11, 17, 33, 51, 187, 561
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,451,561,136, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
451:11x 41
561:3x 11x 17
136:2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 17 = 374
Therefore, the value for common factors is 374.
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 = 30624451440/(1x374)
LCM = 30624451440/374
LCM = 81883560
Thus, we can understand that the LCM of 890,451,561,136 is 81883560.
