Given numbers are 421,358,904,562
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,358,904,562 is 19142994616.
Find LCM of 421,358,904,562 with Prime Factorization
2 | 421, 358, 904, 562 |
421, 179, 452, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 421 x 179 x 452 x 281 = 19142994616
Therefore, the lowest common multiple of 421,358,904,562 is 19142994616.
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 358 x 904 x 562 = 76571978464
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
358 : 1, 2, 179, 358
904 : 1, 2, 4, 8, 113, 226, 452, 904
562 : 1, 2, 281, 562
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,358,904,562, is 1.
Now, the common factors can be found like this.
421:421
358:2x 179
904:2x 2x 2x 113
562:2x 281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 76571978464/(1x4)
LCM = 76571978464/4
LCM = 19142994616
Thus, we can understand that the LCM of 421,358,904,562 is 19142994616.
