Given numbers are 363,942,842,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 363,942,842,421 is 47986422.
Find LCM of 363,942,842,421 with Prime Factorization
| 2 | 363, 942, 842, 421 |
| 3 | 363, 471, 421, 421 |
| 421 | 121, 157, 421, 421 |
| 121, 157, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 421 x 121 x 157 x 1 x 1 = 47986422
Therefore, the lowest common multiple of 363,942,842,421 is 47986422.
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.
363 x 942 x 842 x 421 = 121213701972
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.
363 : 1, 3, 11, 33, 121, 363
942 : 1, 2, 3, 6, 157, 314, 471, 942
842 : 1, 2, 421, 842
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,942,842,421, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
942:2x 3x 157
842:2x 421
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 3x 421 = 2526
Therefore, the value for common factors is 2526.
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 = 121213701972/(1x2526)
LCM = 121213701972/2526
LCM = 47986422
Thus, we can understand that the LCM of 363,942,842,421 is 47986422.
