The LCM of 721,560,991,956,750 is 1024608774000.
Find LCM of 721,560,991,956,750 with Prime Factorization
| 2 | 721, 560, 991, 956, 750 |
| 2 | 721, 280, 991, 478, 375 |
| 5 | 721, 140, 991, 239, 375 |
| 7 | 721, 28, 991, 239, 75 |
| 103, 4, 991, 239, 75 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 103 x 4 x 991 x 239 x 75 = 1024608774000
Therefore, the lowest common multiple of 721,560,991,956,750 is 1024608774000.
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 560 x 991 x 956 x 750 = 286890456720000
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
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
991 : 1, 991
956 : 1, 2, 4, 239, 478, 956
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,560,991,956,750, is 1.
Now, the common factors can be found like this.
721:7x 103
560:2x 2x 2x 2x 5x 7
991:991
956:2x 2x 239
750:2x 3x 5x 5x 5
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 286890456720000/(1x280)
LCM = 286890456720000/280
LCM = 1024608774000
Thus, we can understand that the LCM of 721,560,991,956,750 is 1024608774000.
