Given numbers are 165,781,319,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,781,319,507 is 57415215.
Find LCM of 165,781,319,507 with Prime Factorization
| 3 | 165, 781, 319, 507 |
| 11 | 55, 781, 319, 169 |
| 5, 71, 29, 169 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 5 x 71 x 29 x 169 = 57415215
Therefore, the lowest common multiple of 165,781,319,507 is 57415215.
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.
165 x 781 x 319 x 507 = 20841723045
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
781 : 1, 11, 71, 781
319 : 1, 11, 29, 319
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,781,319,507, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
781:11x 71
319:11x 29
507:3x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 20841723045/(1x363)
LCM = 20841723045/363
LCM = 57415215
Thus, we can understand that the LCM of 165,781,319,507 is 57415215.
