Given numbers are 931,249,252,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,249,252,470 is 653729580.
Find LCM of 931,249,252,470 with Prime Factorization
| 2 | 931, 249, 252, 470 |
| 3 | 931, 249, 126, 235 |
| 7 | 931, 83, 42, 235 |
| 133, 83, 6, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 133 x 83 x 6 x 235 = 653729580
Therefore, the lowest common multiple of 931,249,252,470 is 653729580.
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.
931 x 249 x 252 x 470 = 27456642360
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.
931 : 1, 7, 19, 49, 133, 931
249 : 1, 3, 83, 249
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,249,252,470, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
249:3x 83
252:2x 2x 3x 3x 7
470:2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 27456642360/(1x42)
LCM = 27456642360/42
LCM = 653729580
Thus, we can understand that the LCM of 931,249,252,470 is 653729580.
