Given numbers are 765,719,322,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,719,322,391 is 177111270.
Find LCM of 765,719,322,391 with Prime Factorization
17 | 765, 719, 322, 391 |
23 | 45, 719, 322, 23 |
45, 719, 14, 1 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 45 x 719 x 14 x 1 = 177111270
Therefore, the lowest common multiple of 765,719,322,391 is 177111270.
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.
765 x 719 x 322 x 391 = 69250506570
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
719 : 1, 719
322 : 1, 2, 7, 14, 23, 46, 161, 322
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,719,322,391, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
719:719
322:2x 7x 23
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
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 = 69250506570/(1x391)
LCM = 69250506570/391
LCM = 177111270
Thus, we can understand that the LCM of 765,719,322,391 is 177111270.
