Given numbers are 714,942,720,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 714,942,720,581 is 1116496080.
Find LCM of 714,942,720,581 with Prime Factorization
| 2 | 714, 942, 720, 581 |
| 3 | 357, 471, 360, 581 |
| 7 | 119, 157, 120, 581 |
| 17, 157, 120, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 157 x 120 x 83 = 1116496080
Therefore, the lowest common multiple of 714,942,720,581 is 1116496080.
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.
714 x 942 x 720 x 581 = 281357012160
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
942 : 1, 2, 3, 6, 157, 314, 471, 942
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,942,720,581, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
942:2x 3x 157
720:2x 2x 2x 2x 3x 3x 5
581:7x 83
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 7 = 252
Therefore, the value for common factors is 252.
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 = 281357012160/(1x252)
LCM = 281357012160/252
LCM = 1116496080
Thus, we can understand that the LCM of 714,942,720,581 is 1116496080.
