Given numbers are 856,473,384,505,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,473,384,505,421 is 4131898235520.
Find LCM of 856,473,384,505,421 with Prime Factorization
| 2 | 856, 473, 384, 505, 421 |
| 2 | 428, 473, 192, 505, 421 |
| 2 | 214, 473, 96, 505, 421 |
| 107, 473, 48, 505, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 107 x 473 x 48 x 505 x 421 = 4131898235520
Therefore, the lowest common multiple of 856,473,384,505,421 is 4131898235520.
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.
856 x 473 x 384 x 505 x 421 = 33055185884160
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
473 : 1, 11, 43, 473
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
505 : 1, 5, 101, 505
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,473,384,505,421, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
473:11x 43
384:2x 2x 2x 2x 2x 2x 2x 3
505:5x 101
421:421
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 2 = 8
Therefore, the value for common factors is 8.
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 = 33055185884160/(1x8)
LCM = 33055185884160/8
LCM = 4131898235520
Thus, we can understand that the LCM of 856,473,384,505,421 is 4131898235520.
