Given numbers are 431,660,155,253
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,660,155,253 is 202819980.
Find LCM of 431,660,155,253 with Prime Factorization
5 | 431, 660, 155, 253 |
11 | 431, 132, 31, 253 |
431, 12, 31, 23 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 431 x 12 x 31 x 23 = 202819980
Therefore, the lowest common multiple of 431,660,155,253 is 202819980.
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.
431 x 660 x 155 x 253 = 11155098900
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.
431 : 1, 431
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
155 : 1, 5, 31, 155
253 : 1, 11, 23, 253
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,660,155,253, is 1.
Now, the common factors can be found like this.
431:431
660:2x 2x 3x 5x 11
155:5x 31
253:11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 11155098900/(1x55)
LCM = 11155098900/55
LCM = 202819980
Thus, we can understand that the LCM of 431,660,155,253 is 202819980.
