Given numbers are 407,842,671,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,842,671,917 is 19169274278.
Find LCM of 407,842,671,917 with Prime Factorization
| 11 | 407, 842, 671, 917 |
| 37, 842, 61, 917 |
Multiply the prime numbers at the bottom and the left side.
11 x 37 x 842 x 61 x 917 = 19169274278
Therefore, the lowest common multiple of 407,842,671,917 is 19169274278.
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.
407 x 842 x 671 x 917 = 210862017058
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.
407 : 1, 11, 37, 407
842 : 1, 2, 421, 842
671 : 1, 11, 61, 671
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,842,671,917, is 1.
Now, the common factors can be found like this.
407:11x 37
842:2x 421
671:11x 61
917:7x 131
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 = 210862017058/(1x11)
LCM = 210862017058/11
LCM = 19169274278
Thus, we can understand that the LCM of 407,842,671,917 is 19169274278.
