Given numbers are 920,253,391,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,253,391,505 is 17376040.
Find LCM of 920,253,391,505 with Prime Factorization
5 | 920, 253, 391, 505 |
23 | 184, 253, 391, 101 |
8, 11, 17, 101 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 8 x 11 x 17 x 101 = 17376040
Therefore, the lowest common multiple of 920,253,391,505 is 17376040.
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.
920 x 253 x 391 x 505 = 45959625800
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
253 : 1, 11, 23, 253
391 : 1, 17, 23, 391
505 : 1, 5, 101, 505
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,253,391,505, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
253:11x 23
391:17x 23
505:5x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23x 23 = 2645
Therefore, the value for common factors is 2645.
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 = 45959625800/(1x2645)
LCM = 45959625800/2645
LCM = 17376040
Thus, we can understand that the LCM of 920,253,391,505 is 17376040.
