Given numbers are 901,140,399,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,140,399,285 is 7189980.
Find LCM of 901,140,399,285 with Prime Factorization
3 | 901, 140, 399, 285 |
5 | 901, 140, 133, 95 |
7 | 901, 28, 133, 19 |
19 | 901, 4, 19, 19 |
901, 4, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 901 x 4 x 1 x 1 = 7189980
Therefore, the lowest common multiple of 901,140,399,285 is 7189980.
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 140 x 399 x 285 = 14344010100
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
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
399 : 1, 3, 7, 19, 21, 57, 133, 399
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,140,399,285, is 1.
Now, the common factors can be found like this.
901:17x 53
140:2x 2x 5x 7
399:3x 7x 19
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 19 = 1995
Therefore, the value for common factors is 1995.
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 = 14344010100/(1x1995)
LCM = 14344010100/1995
LCM = 7189980
Thus, we can understand that the LCM of 901,140,399,285 is 7189980.
