Given numbers are 851,989,174,856,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,989,174,856,171 is 155333772072.
Find LCM of 851,989,174,856,171 with Prime Factorization
| 2 | 851, 989, 174, 856, 171 |
| 3 | 851, 989, 87, 428, 171 |
| 23 | 851, 989, 29, 428, 57 |
| 37, 43, 29, 428, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 37 x 43 x 29 x 428 x 57 = 155333772072
Therefore, the lowest common multiple of 851,989,174,856,171 is 155333772072.
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 989 x 174 x 856 x 171 = 21436060545936
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
989 : 1, 23, 43, 989
174 : 1, 2, 3, 6, 29, 58, 87, 174
856 : 1, 2, 4, 8, 107, 214, 428, 856
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,989,174,856,171, is 1.
Now, the common factors can be found like this.
851:23x 37
989:23x 43
174:2x 3x 29
856:2x 2x 2x 107
171:3x 3x 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 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 21436060545936/(1x138)
LCM = 21436060545936/138
LCM = 155333772072
Thus, we can understand that the LCM of 851,989,174,856,171 is 155333772072.
