Given numbers are 851,669,486,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,669,486,144 is 737837424.
Find LCM of 851,669,486,144 with Prime Factorization
| 2 | 851, 669, 486, 144 |
| 3 | 851, 669, 243, 72 |
| 3 | 851, 223, 81, 24 |
| 851, 223, 27, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 851 x 223 x 27 x 8 = 737837424
Therefore, the lowest common multiple of 851,669,486,144 is 737837424.
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 669 x 486 x 144 = 39843220896
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
669 : 1, 3, 223, 669
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,669,486,144, is 1.
Now, the common factors can be found like this.
851:23x 37
669:3x 223
486:2x 3x 3x 3x 3x 3
144:2x 2x 2x 2x 3x 3
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 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 39843220896/(1x54)
LCM = 39843220896/54
LCM = 737837424
Thus, we can understand that the LCM of 851,669,486,144 is 737837424.
