Find LCM of 720,310,181,760,690 with Prime Factorization
| 2 | 720, 310, 181, 760, 690 |
| 2 | 360, 155, 181, 380, 345 |
| 2 | 180, 155, 181, 190, 345 |
| 3 | 90, 155, 181, 95, 345 |
| 5 | 30, 155, 181, 95, 115 |
| 6, 31, 181, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 6 x 31 x 181 x 19 x 23 = 1765445040
Therefore, the lowest common multiple of 720,310,181,760,690 is 1765445040.
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 310 x 181 x 760 x 690 = 21185340480000
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
310 : 1, 2, 5, 10, 31, 62, 155, 310
181 : 1, 181
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,310,181,760,690, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
310:2x 5x 31
181:181
760:2x 2x 2x 5x 19
690:2x 3x 5x 23
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 3x 5x 5x 5 = 12000
Therefore, the value for common factors is 12000.
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 = 21185340480000/(1x12000)
LCM = 21185340480000/12000
LCM = 1765445040
Thus, we can understand that the LCM of 720,310,181,760,690 is 1765445040.
