Given numbers are 713,180,805,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 713,180,805,764 is 171590580.
Find LCM of 713,180,805,764 with Prime Factorization
| 2 | 713, 180, 805, 764 |
| 2 | 713, 90, 805, 382 |
| 5 | 713, 45, 805, 191 |
| 23 | 713, 9, 161, 191 |
| 31, 9, 7, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 31 x 9 x 7 x 191 = 171590580
Therefore, the lowest common multiple of 713,180,805,764 is 171590580.
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.
713 x 180 x 805 x 764 = 78931666800
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.
713 : 1, 23, 31, 713
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
805 : 1, 5, 7, 23, 35, 115, 161, 805
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,180,805,764, is 1.
Now, the common factors can be found like this.
713:23x 31
180:2x 2x 3x 3x 5
805:5x 7x 23
764:2x 2x 191
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 78931666800/(1x460)
LCM = 78931666800/460
LCM = 171590580
Thus, we can understand that the LCM of 713,180,805,764 is 171590580.
