Given numbers are 901,901,789,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,901,789,644 is 457812516.
Find LCM of 901,901,789,644 with Prime Factorization
| 17 | 901, 901, 789, 644 |
| 53 | 53, 53, 789, 644 |
| 1, 1, 789, 644 |
Multiply the prime numbers at the bottom and the left side.
17 x 53 x 1 x 1 x 789 x 644 = 457812516
Therefore, the lowest common multiple of 901,901,789,644 is 457812516.
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.
901 x 901 x 789 x 644 = 412489076916
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.
901 : 1, 17, 53, 901
901 : 1, 17, 53, 901
789 : 1, 3, 263, 789
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,901,789,644, is 1.
Now, the common factors can be found like this.
901:17x 53
901:17x 53
789:3x 263
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 53 = 901
Therefore, the value for common factors is 901.
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 = 412489076916/(1x901)
LCM = 412489076916/901
LCM = 457812516
Thus, we can understand that the LCM of 901,901,789,644 is 457812516.
