Given numbers are 844,108,136,665,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,108,136,665,781 is 402399847080.
Find LCM of 844,108,136,665,781 with Prime Factorization
| 2 | 844, 108, 136, 665, 781 |
| 2 | 422, 54, 68, 665, 781 |
| 211, 27, 34, 665, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 211 x 27 x 34 x 665 x 781 = 402399847080
Therefore, the lowest common multiple of 844,108,136,665,781 is 402399847080.
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.
844 x 108 x 136 x 665 x 781 = 6438397553280
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.
844 : 1, 2, 4, 211, 422, 844
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
136 : 1, 2, 4, 8, 17, 34, 68, 136
665 : 1, 5, 7, 19, 35, 95, 133, 665
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,108,136,665,781, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
108:2x 2x 3x 3x 3
136:2x 2x 2x 17
665:5x 7x 19
781:11x 71
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 2 = 16
Therefore, the value for common factors is 16.
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 = 6438397553280/(1x16)
LCM = 6438397553280/16
LCM = 402399847080
Thus, we can understand that the LCM of 844,108,136,665,781 is 402399847080.
