Given numbers are 102,136,786,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,136,786,220 is 2939640.
Find LCM of 102,136,786,220 with Prime Factorization
| 2 | 102, 136, 786, 220 |
| 2 | 51, 68, 393, 110 |
| 3 | 51, 34, 393, 55 |
| 17 | 17, 34, 131, 55 |
| 1, 2, 131, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 1 x 2 x 131 x 55 = 2939640
Therefore, the lowest common multiple of 102,136,786,220 is 2939640.
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.
102 x 136 x 786 x 220 = 2398746240
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
136 : 1, 2, 4, 8, 17, 34, 68, 136
786 : 1, 2, 3, 6, 131, 262, 393, 786
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,136,786,220, is 2.
Now, the common factors can be found like this.
102:2x 3x 17
136:2x 2x 2x 17
786:2x 3x 131
220:2x 2x 5x 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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 2398746240/(2x408)
LCM = 2398746240/816
LCM = 2939640
Thus, we can understand that the LCM of 102,136,786,220 is 2939640.
