Given numbers are 851,116,856,392
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,116,856,392 is 1035135976.
Find LCM of 851,116,856,392 with Prime Factorization
| 2 | 851, 116, 856, 392 |
| 2 | 851, 58, 428, 196 |
| 2 | 851, 29, 214, 98 |
| 851, 29, 107, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 851 x 29 x 107 x 49 = 1035135976
Therefore, the lowest common multiple of 851,116,856,392 is 1035135976.
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.
851 x 116 x 856 x 392 = 33124351232
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.
851 : 1, 23, 37, 851
116 : 1, 2, 4, 29, 58, 116
856 : 1, 2, 4, 8, 107, 214, 428, 856
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,116,856,392, is 1.
Now, the common factors can be found like this.
851:23x 37
116:2x 2x 29
856:2x 2x 2x 107
392:2x 2x 2x 7x 7
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 2 = 32
Therefore, the value for common factors is 32.
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 = 33124351232/(1x32)
LCM = 33124351232/32
LCM = 1035135976
Thus, we can understand that the LCM of 851,116,856,392 is 1035135976.
