Given numbers are 427,228,686,245,607
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 427,228,686,245,607 is 14478297540.
Find LCM of 427,228,686,245,607 with Prime Factorization
| 2 | 427, 228, 686, 245, 607 |
| 7 | 427, 114, 343, 245, 607 |
| 7 | 61, 114, 49, 35, 607 |
| 61, 114, 7, 5, 607 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 61 x 114 x 7 x 5 x 607 = 14478297540
Therefore, the lowest common multiple of 427,228,686,245,607 is 14478297540.
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.
427 x 228 x 686 x 245 x 607 = 9932112112440
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.
427 : 1, 7, 61, 427
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
686 : 1, 2, 7, 14, 49, 98, 343, 686
245 : 1, 5, 7, 35, 49, 245
607 : 1, 607
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,228,686,245,607, is 1.
Now, the common factors can be found like this.
427:7x 61
228:2x 2x 3x 19
686:2x 7x 7x 7
245:5x 7x 7
607:607
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 7 = 686
Therefore, the value for common factors is 686.
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 = 9932112112440/(1x686)
LCM = 9932112112440/686
LCM = 14478297540
Thus, we can understand that the LCM of 427,228,686,245,607 is 14478297540.
