Given numbers are 202,969,136,780,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,969,136,780,646 is 50891880.
Find LCM of 202,969,136,780,646 with Prime Factorization
| 2 | 202, 969, 136, 780, 646 |
| 2 | 101, 969, 68, 390, 323 |
| 3 | 101, 969, 34, 195, 323 |
| 17 | 101, 323, 34, 65, 323 |
| 19 | 101, 19, 2, 65, 19 |
| 101, 1, 2, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 19 x 101 x 1 x 2 x 65 x 1 = 50891880
Therefore, the lowest common multiple of 202,969,136,780,646 is 50891880.
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.
202 x 969 x 136 x 780 x 646 = 13413471027840
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.
202 : 1, 2, 101, 202
969 : 1, 3, 17, 19, 51, 57, 323, 969
136 : 1, 2, 4, 8, 17, 34, 68, 136
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,969,136,780,646, is 1.
Now, the common factors can be found like this.
202:2x 101
969:3x 17x 19
136:2x 2x 2x 17
780:2x 2x 3x 5x 13
646:2x 17x 19
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 2x 3x 17x 17x 19 = 263568
Therefore, the value for common factors is 263568.
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 = 13413471027840/(1x263568)
LCM = 13413471027840/263568
LCM = 50891880
Thus, we can understand that the LCM of 202,969,136,780,646 is 50891880.
