Given numbers are 731,720,336,716
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,720,336,716 is 659478960.
Find LCM of 731,720,336,716 with Prime Factorization
| 2 | 731, 720, 336, 716 |
| 2 | 731, 360, 168, 358 |
| 2 | 731, 180, 84, 179 |
| 2 | 731, 90, 42, 179 |
| 3 | 731, 45, 21, 179 |
| 731, 15, 7, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 731 x 15 x 7 x 179 = 659478960
Therefore, the lowest common multiple of 731,720,336,716 is 659478960.
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.
731 x 720 x 336 x 716 = 126619960320
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.
731 : 1, 17, 43, 731
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,720,336,716, is 1.
Now, the common factors can be found like this.
731:17x 43
720:2x 2x 2x 2x 3x 3x 5
336:2x 2x 2x 2x 3x 7
716:2x 2x 179
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 126619960320/(1x192)
LCM = 126619960320/192
LCM = 659478960
Thus, we can understand that the LCM of 731,720,336,716 is 659478960.
