Given numbers are 123,136,130,868,377
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,136,130,868,377 is 6842504760.
Find LCM of 123,136,130,868,377 with Prime Factorization
| 2 | 123, 136, 130, 868, 377 |
| 2 | 123, 68, 65, 434, 377 |
| 13 | 123, 34, 65, 217, 377 |
| 123, 34, 5, 217, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 123 x 34 x 5 x 217 x 29 = 6842504760
Therefore, the lowest common multiple of 123,136,130,868,377 is 6842504760.
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.
123 x 136 x 130 x 868 x 377 = 711620495040
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.
123 : 1, 3, 41, 123
136 : 1, 2, 4, 8, 17, 34, 68, 136
130 : 1, 2, 5, 10, 13, 26, 65, 130
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,136,130,868,377, is 1.
Now, the common factors can be found like this.
123:3x 41
136:2x 2x 2x 17
130:2x 5x 13
868:2x 2x 7x 31
377:13x 29
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 13 = 104
Therefore, the value for common factors is 104.
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 = 711620495040/(1x104)
LCM = 711620495040/104
LCM = 6842504760
Thus, we can understand that the LCM of 123,136,130,868,377 is 6842504760.
