Given numbers are 407,942,618,533
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 407,942,618,533 is 21047947206.
Find LCM of 407,942,618,533 with Prime Factorization
| 2 | 407, 942, 618, 533 |
| 3 | 407, 471, 309, 533 |
| 407, 157, 103, 533 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 407 x 157 x 103 x 533 = 21047947206
Therefore, the lowest common multiple of 407,942,618,533 is 21047947206.
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 942 x 618 x 533 = 126287683236
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
618 : 1, 2, 3, 6, 103, 206, 309, 618
533 : 1, 13, 41, 533
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,942,618,533, is 1.
Now, the common factors can be found like this.
407:11x 37
942:2x 3x 157
618:2x 3x 103
533:13x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 126287683236/(1x6)
LCM = 126287683236/6
LCM = 21047947206
Thus, we can understand that the LCM of 407,942,618,533 is 21047947206.
