Given numbers are 974,800,731,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,800,731,436 is 31042938400.
Find LCM of 974,800,731,436 with Prime Factorization
| 2 | 974, 800, 731, 436 |
| 2 | 487, 400, 731, 218 |
| 487, 200, 731, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 487 x 200 x 731 x 109 = 31042938400
Therefore, the lowest common multiple of 974,800,731,436 is 31042938400.
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.
974 x 800 x 731 x 436 = 248343507200
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.
974 : 1, 2, 487, 974
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
731 : 1, 17, 43, 731
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,800,731,436, is 1.
Now, the common factors can be found like this.
974:2x 487
800:2x 2x 2x 2x 2x 5x 5
731:17x 43
436:2x 2x 109
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 2 = 8
Therefore, the value for common factors is 8.
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 = 248343507200/(1x8)
LCM = 248343507200/8
LCM = 31042938400
Thus, we can understand that the LCM of 974,800,731,436 is 31042938400.
