Given numbers are 389,635,901,844,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,635,901,844,980 is 9204212658340.
Find LCM of 389,635,901,844,980 with Prime Factorization
| 2 | 389, 635, 901, 844, 980 |
| 2 | 389, 635, 901, 422, 490 |
| 5 | 389, 635, 901, 211, 245 |
| 389, 127, 901, 211, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 389 x 127 x 901 x 211 x 49 = 9204212658340
Therefore, the lowest common multiple of 389,635,901,844,980 is 9204212658340.
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.
389 x 635 x 901 x 844 x 980 = 184084253166800
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.
389 : 1, 389
635 : 1, 5, 127, 635
901 : 1, 17, 53, 901
844 : 1, 2, 4, 211, 422, 844
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,635,901,844,980, is 1.
Now, the common factors can be found like this.
389:389
635:5x 127
901:17x 53
844:2x 2x 211
980:2x 2x 5x 7x 7
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 5 = 20
Therefore, the value for common factors is 20.
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 = 184084253166800/(1x20)
LCM = 184084253166800/20
LCM = 9204212658340
Thus, we can understand that the LCM of 389,635,901,844,980 is 9204212658340.
