Given numbers are 720,811,769,746,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,811,769,746,147 is 8207003190960.
Find LCM of 720,811,769,746,147 with Prime Factorization
| 2 | 720, 811, 769, 746, 147 |
| 3 | 360, 811, 769, 373, 147 |
| 120, 811, 769, 373, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 120 x 811 x 769 x 373 x 49 = 8207003190960
Therefore, the lowest common multiple of 720,811,769,746,147 is 8207003190960.
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.
720 x 811 x 769 x 746 x 147 = 49242019145760
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.
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
811 : 1, 811
769 : 1, 769
746 : 1, 2, 373, 746
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,811,769,746,147, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
811:811
769:769
746:2x 373
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 49242019145760/(1x6)
LCM = 49242019145760/6
LCM = 8207003190960
Thus, we can understand that the LCM of 720,811,769,746,147 is 8207003190960.
