Given numbers are 561,377,320,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,377,320,871 is 4534495680.
Find LCM of 561,377,320,871 with Prime Factorization
13 | 561, 377, 320, 871 |
561, 29, 320, 67 |
Multiply the prime numbers at the bottom and the left side.
13 x 561 x 29 x 320 x 67 = 4534495680
Therefore, the lowest common multiple of 561,377,320,871 is 4534495680.
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.
561 x 377 x 320 x 871 = 58948443840
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
377 : 1, 13, 29, 377
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,377,320,871, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
377:13x 29
320:2x 2x 2x 2x 2x 2x 5
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 58948443840/(1x13)
LCM = 58948443840/13
LCM = 4534495680
Thus, we can understand that the LCM of 561,377,320,871 is 4534495680.
