Given numbers are 421,508,561,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,508,561,979 is 10678215372.
Find LCM of 421,508,561,979 with Prime Factorization
11 | 421, 508, 561, 979 |
421, 508, 51, 89 |
Multiply the prime numbers at the bottom and the left side.
11 x 421 x 508 x 51 x 89 = 10678215372
Therefore, the lowest common multiple of 421,508,561,979 is 10678215372.
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.
421 x 508 x 561 x 979 = 117460369092
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.
421 : 1, 421
508 : 1, 2, 4, 127, 254, 508
561 : 1, 3, 11, 17, 33, 51, 187, 561
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,508,561,979, is 1.
Now, the common factors can be found like this.
421:421
508:2x 2x 127
561:3x 11x 17
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 117460369092/(1x11)
LCM = 117460369092/11
LCM = 10678215372
Thus, we can understand that the LCM of 421,508,561,979 is 10678215372.
