Given numbers are 721,392,717,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,392,717,288 is 347395104.
Find LCM of 721,392,717,288 with Prime Factorization
2 | 721, 392, 717, 288 |
2 | 721, 196, 717, 144 |
2 | 721, 98, 717, 72 |
3 | 721, 49, 717, 36 |
7 | 721, 49, 239, 12 |
103, 7, 239, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 103 x 7 x 239 x 12 = 347395104
Therefore, the lowest common multiple of 721,392,717,288 is 347395104.
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.
721 x 392 x 717 x 288 = 58362377472
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.
721 : 1, 7, 103, 721
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
717 : 1, 3, 239, 717
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,392,717,288, is 1.
Now, the common factors can be found like this.
721:7x 103
392:2x 2x 2x 7x 7
717:3x 239
288:2x 2x 2x 2x 2x 3x 3
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 58362377472/(1x168)
LCM = 58362377472/168
LCM = 347395104
Thus, we can understand that the LCM of 721,392,717,288 is 347395104.
