Given numbers are 201,715,921,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 201,715,921,680 is 6000388680.
Find LCM of 201,715,921,680 with Prime Factorization
| 3 | 201, 715, 921, 680 |
| 5 | 67, 715, 307, 680 |
| 67, 143, 307, 136 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 67 x 143 x 307 x 136 = 6000388680
Therefore, the lowest common multiple of 201,715,921,680 is 6000388680.
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.
201 x 715 x 921 x 680 = 90005830200
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.
201 : 1, 3, 67, 201
715 : 1, 5, 11, 13, 55, 65, 143, 715
921 : 1, 3, 307, 921
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,715,921,680, is 1.
Now, the common factors can be found like this.
201:3x 67
715:5x 11x 13
921:3x 307
680:2x 2x 2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 90005830200/(1x15)
LCM = 90005830200/15
LCM = 6000388680
Thus, we can understand that the LCM of 201,715,921,680 is 6000388680.
