Given numbers are 864,770,690,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,770,690,901 is 6893298720.
Find LCM of 864,770,690,901 with Prime Factorization
| 2 | 864, 770, 690, 901 |
| 3 | 432, 385, 345, 901 |
| 5 | 144, 385, 115, 901 |
| 144, 77, 23, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 144 x 77 x 23 x 901 = 6893298720
Therefore, the lowest common multiple of 864,770,690,901 is 6893298720.
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.
864 x 770 x 690 x 901 = 413597923200
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,770,690,901, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
770:2x 5x 7x 11
690:2x 3x 5x 23
901:17x 53
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 5 = 60
Therefore, the value for common factors is 60.
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 = 413597923200/(1x60)
LCM = 413597923200/60
LCM = 6893298720
Thus, we can understand that the LCM of 864,770,690,901 is 6893298720.
