Given numbers are 471,620,248,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 471,620,248,634 is 185140680.
Find LCM of 471,620,248,634 with Prime Factorization
| 2 | 471, 620, 248, 634 |
| 2 | 471, 310, 124, 317 |
| 31 | 471, 155, 62, 317 |
| 471, 5, 2, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 471 x 5 x 2 x 317 = 185140680
Therefore, the lowest common multiple of 471,620,248,634 is 185140680.
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.
471 x 620 x 248 x 634 = 45914888640
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.
471 : 1, 3, 157, 471
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
248 : 1, 2, 4, 8, 31, 62, 124, 248
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,620,248,634, is 1.
Now, the common factors can be found like this.
471:3x 157
620:2x 2x 5x 31
248:2x 2x 2x 31
634:2x 317
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 2x 31 = 248
Therefore, the value for common factors is 248.
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 = 45914888640/(1x248)
LCM = 45914888640/248
LCM = 185140680
Thus, we can understand that the LCM of 471,620,248,634 is 185140680.
