Given numbers are 721,252,262,640,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,252,262,640,849 is 153962686080.
Find LCM of 721,252,262,640,849 with Prime Factorization
| 2 | 721, 252, 262, 640, 849 |
| 2 | 721, 126, 131, 320, 849 |
| 3 | 721, 63, 131, 160, 849 |
| 7 | 721, 21, 131, 160, 283 |
| 103, 3, 131, 160, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 103 x 3 x 131 x 160 x 283 = 153962686080
Therefore, the lowest common multiple of 721,252,262,640,849 is 153962686080.
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.
721 x 252 x 262 x 640 x 849 = 25865731261440
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.
721 : 1, 7, 103, 721
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
262 : 1, 2, 131, 262
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,252,262,640,849, is 1.
Now, the common factors can be found like this.
721:7x 103
252:2x 2x 3x 3x 7
262:2x 131
640:2x 2x 2x 2x 2x 2x 2x 5
849:3x 283
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 7 = 168
Therefore, the value for common factors is 168.
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 = 25865731261440/(1x168)
LCM = 25865731261440/168
LCM = 153962686080
Thus, we can understand that the LCM of 721,252,262,640,849 is 153962686080.
