Given numbers are 720,861,713,300
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,861,713,300 is 736671600.
Find LCM of 720,861,713,300 with Prime Factorization
| 2 | 720, 861, 713, 300 |
| 2 | 360, 861, 713, 150 |
| 3 | 180, 861, 713, 75 |
| 5 | 60, 287, 713, 25 |
| 12, 287, 713, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 12 x 287 x 713 x 5 = 736671600
Therefore, the lowest common multiple of 720,861,713,300 is 736671600.
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.
720 x 861 x 713 x 300 = 132600888000
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.
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
713 : 1, 23, 31, 713
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,861,713,300, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
861:3x 7x 41
713:23x 31
300:2x 2x 3x 5x 5
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 5 = 180
Therefore, the value for common factors is 180.
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 = 132600888000/(1x180)
LCM = 132600888000/180
LCM = 736671600
Thus, we can understand that the LCM of 720,861,713,300 is 736671600.
