Given numbers are 890,424,845,812,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 890,424,845,812,121 is 783238415960.
Find LCM of 890,424,845,812,121 with Prime Factorization
| 2 | 890, 424, 845, 812, 121 |
| 2 | 445, 212, 845, 406, 121 |
| 5 | 445, 106, 845, 203, 121 |
| 89, 106, 169, 203, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 89 x 106 x 169 x 203 x 121 = 783238415960
Therefore, the lowest common multiple of 890,424,845,812,121 is 783238415960.
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 424 x 845 x 812 x 121 = 31329536638400
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
424 : 1, 2, 4, 8, 53, 106, 212, 424
845 : 1, 5, 13, 65, 169, 845
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,424,845,812,121, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
424:2x 2x 2x 53
845:5x 13x 13
812:2x 2x 7x 29
121:11x 11
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 5 = 40
Therefore, the value for common factors is 40.
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 = 31329536638400/(1x40)
LCM = 31329536638400/40
LCM = 783238415960
Thus, we can understand that the LCM of 890,424,845,812,121 is 783238415960.
