Given numbers are 869,476,561,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,476,561,100 is 31023300.
Find LCM of 869,476,561,100 with Prime Factorization
2 | 869, 476, 561, 100 |
2 | 869, 238, 561, 50 |
11 | 869, 119, 561, 25 |
17 | 79, 119, 51, 25 |
79, 7, 3, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 79 x 7 x 3 x 25 = 31023300
Therefore, the lowest common multiple of 869,476,561,100 is 31023300.
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.
869 x 476 x 561 x 100 = 23205428400
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.
869 : 1, 11, 79, 869
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
561 : 1, 3, 11, 17, 33, 51, 187, 561
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,476,561,100, is 1.
Now, the common factors can be found like this.
869:11x 79
476:2x 2x 7x 17
561:3x 11x 17
100:2x 2x 5x 5
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 23205428400/(1x748)
LCM = 23205428400/748
LCM = 31023300
Thus, we can understand that the LCM of 869,476,561,100 is 31023300.
