Given numbers are 621,247,487,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,247,487,793 is 4556667609.
Find LCM of 621,247,487,793 with Prime Factorization
13 | 621, 247, 487, 793 |
621, 19, 487, 61 |
Multiply the prime numbers at the bottom and the left side.
13 x 621 x 19 x 487 x 61 = 4556667609
Therefore, the lowest common multiple of 621,247,487,793 is 4556667609.
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.
621 x 247 x 487 x 793 = 59236678917
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
247 : 1, 13, 19, 247
487 : 1, 487
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,247,487,793, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
247:13x 19
487:487
793:13x 61
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 = 59236678917/(1x13)
LCM = 59236678917/13
LCM = 4556667609
Thus, we can understand that the LCM of 621,247,487,793 is 4556667609.
