Given numbers are 220,917,777,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,917,777,851 is 515042220.
Find LCM of 220,917,777,851 with Prime Factorization
| 7 | 220, 917, 777, 851 |
| 37 | 220, 131, 111, 851 |
| 220, 131, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
7 x 37 x 220 x 131 x 3 x 23 = 515042220
Therefore, the lowest common multiple of 220,917,777,851 is 515042220.
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.
220 x 917 x 777 x 851 = 133395934980
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
917 : 1, 7, 131, 917
777 : 1, 3, 7, 21, 37, 111, 259, 777
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,917,777,851, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
917:7x 131
777:3x 7x 37
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 37 = 259
Therefore, the value for common factors is 259.
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 = 133395934980/(1x259)
LCM = 133395934980/259
LCM = 515042220
Thus, we can understand that the LCM of 220,917,777,851 is 515042220.
