Given numbers are 4,931,812,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4,931,812,209 is 1187956.
Find LCM of 4,931,812,209 with Prime Factorization
| 2 | 4, 931, 812, 209 |
| 2 | 2, 931, 406, 209 |
| 7 | 1, 931, 203, 209 |
| 19 | 1, 133, 29, 209 |
| 1, 7, 29, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 1 x 7 x 29 x 11 = 1187956
Therefore, the lowest common multiple of 4,931,812,209 is 1187956.
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.
4 x 931 x 812 x 209 = 631992592
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.
4 : 1, 2, 4
931 : 1, 7, 19, 49, 133, 931
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4,931,812,209, is 1.
Now, the common factors can be found like this.
4:2x 2
931:7x 7x 19
812:2x 2x 7x 29
209:11x 19
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 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 631992592/(1x532)
LCM = 631992592/532
LCM = 1187956
Thus, we can understand that the LCM of 4,931,812,209 is 1187956.
