Given numbers are 643,940,533,504,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,940,533,504,901 is 36573066162360.
Find LCM of 643,940,533,504,901 with Prime Factorization
| 2 | 643, 940, 533, 504, 901 |
| 2 | 643, 470, 533, 252, 901 |
| 643, 235, 533, 126, 901 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 643 x 235 x 533 x 126 x 901 = 36573066162360
Therefore, the lowest common multiple of 643,940,533,504,901 is 36573066162360.
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.
643 x 940 x 533 x 504 x 901 = 146292264649440
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.
643 : 1, 643
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
533 : 1, 13, 41, 533
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,940,533,504,901, is 1.
Now, the common factors can be found like this.
643:643
940:2x 2x 5x 47
533:13x 41
504:2x 2x 2x 3x 3x 7
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 2 = 4
Therefore, the value for common factors is 4.
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 = 146292264649440/(1x4)
LCM = 146292264649440/4
LCM = 36573066162360
Thus, we can understand that the LCM of 643,940,533,504,901 is 36573066162360.
