Given numbers are 842,458,427,506,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,458,427,506,421 is 20830321358.
Find LCM of 842,458,427,506,421 with Prime Factorization
| 2 | 842, 458, 427, 506, 421 |
| 421 | 421, 229, 427, 253, 421 |
| 1, 229, 427, 253, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 421 x 1 x 229 x 427 x 253 x 1 = 20830321358
Therefore, the lowest common multiple of 842,458,427,506,421 is 20830321358.
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.
842 x 458 x 427 x 506 x 421 = 35078261166872
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.
842 : 1, 2, 421, 842
458 : 1, 2, 229, 458
427 : 1, 7, 61, 427
506 : 1, 2, 11, 22, 23, 46, 253, 506
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,458,427,506,421, is 1.
Now, the common factors can be found like this.
842:2x 421
458:2x 229
427:7x 61
506:2x 11x 23
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 421 = 1684
Therefore, the value for common factors is 1684.
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 = 35078261166872/(1x1684)
LCM = 35078261166872/1684
LCM = 20830321358
Thus, we can understand that the LCM of 842,458,427,506,421 is 20830321358.
