Given numbers are 507,972,396,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,972,396,847 is 139134996.
Find LCM of 507,972,396,847 with Prime Factorization
| 2 | 507, 972, 396, 847 |
| 2 | 507, 486, 198, 847 |
| 3 | 507, 243, 99, 847 |
| 3 | 169, 81, 33, 847 |
| 11 | 169, 27, 11, 847 |
| 169, 27, 1, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 169 x 27 x 1 x 77 = 139134996
Therefore, the lowest common multiple of 507,972,396,847 is 139134996.
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.
507 x 972 x 396 x 847 = 165292375248
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.
507 : 1, 3, 13, 39, 169, 507
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,972,396,847, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
972:2x 2x 3x 3x 3x 3x 3
396:2x 2x 3x 3x 11
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 11 = 1188
Therefore, the value for common factors is 1188.
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 = 165292375248/(1x1188)
LCM = 165292375248/1188
LCM = 139134996
Thus, we can understand that the LCM of 507,972,396,847 is 139134996.
