Given numbers are 935,420,257,818,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 935,420,257,818,842 is 3475597083420.
Find LCM of 935,420,257,818,842 with Prime Factorization
| 2 | 935, 420, 257, 818, 842 |
| 5 | 935, 210, 257, 409, 421 |
| 187, 42, 257, 409, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 187 x 42 x 257 x 409 x 421 = 3475597083420
Therefore, the lowest common multiple of 935,420,257,818,842 is 3475597083420.
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.
935 x 420 x 257 x 818 x 842 = 69511941668400
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.
935 : 1, 5, 11, 17, 55, 85, 187, 935
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
257 : 1, 257
818 : 1, 2, 409, 818
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 935,420,257,818,842, is 1.
Now, the common factors can be found like this.
935:5x 11x 17
420:2x 2x 3x 5x 7
257:257
818:2x 409
842:2x 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 5 = 20
Therefore, the value for common factors is 20.
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 = 69511941668400/(1x20)
LCM = 69511941668400/20
LCM = 3475597083420
Thus, we can understand that the LCM of 935,420,257,818,842 is 3475597083420.
