Given numbers are 646,871,862,262,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,871,862,262,655 is 158843425130.
Find LCM of 646,871,862,262,655 with Prime Factorization
| 2 | 646, 871, 862, 262, 655 |
| 131 | 323, 871, 431, 131, 655 |
| 323, 871, 431, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 323 x 871 x 431 x 1 x 5 = 158843425130
Therefore, the lowest common multiple of 646,871,862,262,655 is 158843425130.
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.
646 x 871 x 862 x 262 x 655 = 83233954768120
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
871 : 1, 13, 67, 871
862 : 1, 2, 431, 862
262 : 1, 2, 131, 262
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,871,862,262,655, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
871:13x 67
862:2x 431
262:2x 131
655:5x 131
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 131 = 524
Therefore, the value for common factors is 524.
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 = 83233954768120/(1x524)
LCM = 83233954768120/524
LCM = 158843425130
Thus, we can understand that the LCM of 646,871,862,262,655 is 158843425130.
