Given numbers are 850,842,401,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,842,401,974 is 69883452950.
Find LCM of 850,842,401,974 with Prime Factorization
| 2 | 850, 842, 401, 974 |
| 425, 421, 401, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 425 x 421 x 401 x 487 = 69883452950
Therefore, the lowest common multiple of 850,842,401,974 is 69883452950.
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.
850 x 842 x 401 x 974 = 279533811800
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
842 : 1, 2, 421, 842
401 : 1, 401
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,842,401,974, is 1.
Now, the common factors can be found like this.
850:2x 5x 5x 17
842:2x 421
401:401
974:2x 487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 279533811800/(1x4)
LCM = 279533811800/4
LCM = 69883452950
Thus, we can understand that the LCM of 850,842,401,974 is 69883452950.
