Given numbers are 7,216,851,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,216,851,973 is 178852968.
Find LCM of 7,216,851,973 with Prime Factorization
| 7 | 7, 216, 851, 973 |
| 1, 216, 851, 139 |
Multiply the prime numbers at the bottom and the left side.
7 x 1 x 216 x 851 x 139 = 178852968
Therefore, the lowest common multiple of 7,216,851,973 is 178852968.
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.
7 x 216 x 851 x 973 = 1251970776
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.
7 : 1, 7
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
851 : 1, 23, 37, 851
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,216,851,973, is 1.
Now, the common factors can be found like this.
7:7
216:2x 2x 2x 3x 3x 3
851:23x 37
973:7x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 1251970776/(1x7)
LCM = 1251970776/7
LCM = 178852968
Thus, we can understand that the LCM of 7,216,851,973 is 178852968.
