Given numbers are 821,254,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,254,476 is 49631092.
Find LCM of 821,254,476 with Prime Factorization
| 2 | 821, 254, 476 |
| 821, 127, 238 |
Multiply the prime numbers at the bottom and the left side.
2 x 821 x 127 x 238 = 49631092
Therefore, the lowest common multiple of 821,254,476 is 49631092.
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.
821 x 254 x 476 = 99262184
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.
821 : 1, 821
254 : 1, 2, 127, 254
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,254,476, is 1.
Now, the common factors can be found like this.
821:821
254:2x 127
476:2x 2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 99262184/(1x2)
LCM = 99262184/2
LCM = 49631092
Thus, we can understand that the LCM of 821,254,476 is 49631092.
