Given numbers are 857,611,978,130
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 857,611,978,130 is 2560536030.
Find LCM of 857,611,978,130 with Prime Factorization
| 2 | 857, 611, 978, 130 |
| 13 | 857, 611, 489, 65 |
| 857, 47, 489, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 857 x 47 x 489 x 5 = 2560536030
Therefore, the lowest common multiple of 857,611,978,130 is 2560536030.
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.
857 x 611 x 978 x 130 = 66573936780
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.
857 : 1, 857
611 : 1, 13, 47, 611
978 : 1, 2, 3, 6, 163, 326, 489, 978
130 : 1, 2, 5, 10, 13, 26, 65, 130
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,611,978,130, is 1.
Now, the common factors can be found like this.
857:857
611:13x 47
978:2x 3x 163
130:2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 66573936780/(1x26)
LCM = 66573936780/26
LCM = 2560536030
Thus, we can understand that the LCM of 857,611,978,130 is 2560536030.
