Given numbers are 722,717,456,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,717,456,717 is 2070696.
Find LCM of 722,717,456,717 with Prime Factorization
| 2 | 722, 717, 456, 717 |
| 3 | 361, 717, 228, 717 |
| 19 | 361, 239, 76, 239 |
| 239 | 19, 239, 4, 239 |
| 19, 1, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 239 x 19 x 1 x 4 x 1 = 2070696
Therefore, the lowest common multiple of 722,717,456,717 is 2070696.
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.
722 x 717 x 456 x 717 = 169254549648
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.
722 : 1, 2, 19, 38, 361, 722
717 : 1, 3, 239, 717
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,717,456,717, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
717:3x 239
456:2x 2x 2x 3x 19
717:3x 239
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 3x 19x 239 = 81738
Therefore, the value for common factors is 81738.
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 = 169254549648/(1x81738)
LCM = 169254549648/81738
LCM = 2070696
Thus, we can understand that the LCM of 722,717,456,717 is 2070696.
