Given numbers are 301,847,552,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 301,847,552,989 is 20104392.
Find LCM of 301,847,552,989 with Prime Factorization
| 7 | 301, 847, 552, 989 |
| 23 | 43, 121, 552, 989 |
| 43 | 43, 121, 24, 43 |
| 1, 121, 24, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 43 x 1 x 121 x 24 x 1 = 20104392
Therefore, the lowest common multiple of 301,847,552,989 is 20104392.
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.
301 x 847 x 552 x 989 = 139182705816
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.
301 : 1, 7, 43, 301
847 : 1, 7, 11, 77, 121, 847
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 301,847,552,989, is 1.
Now, the common factors can be found like this.
301:7x 43
847:7x 11x 11
552:2x 2x 2x 3x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 23x 43 = 6923
Therefore, the value for common factors is 6923.
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 = 139182705816/(1x6923)
LCM = 139182705816/6923
LCM = 20104392
Thus, we can understand that the LCM of 301,847,552,989 is 20104392.
