Find LCM of 694,764,341,720,648 with Prime Factorization
| 2 | 694, 764, 341, 720, 648 |
| 2 | 347, 382, 341, 360, 324 |
| 2 | 347, 191, 341, 180, 162 |
| 3 | 347, 191, 341, 90, 81 |
| 3 | 347, 191, 341, 30, 27 |
| 347, 191, 341, 10, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 347 x 191 x 341 x 10 x 9 = 146450961360
Therefore, the lowest common multiple of 694,764,341,720,648 is 146450961360.
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.
694 x 764 x 341 x 720 x 648 = 84355753743360
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.
694 : 1, 2, 347, 694
764 : 1, 2, 4, 191, 382, 764
341 : 1, 11, 31, 341
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,764,341,720,648, is 1.
Now, the common factors can be found like this.
694:2x 347
764:2x 2x 191
341:11x 31
720:2x 2x 2x 2x 3x 3x 5
648:2x 2x 2x 3x 3x 3x 3
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 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 84355753743360/(1x576)
LCM = 84355753743360/576
LCM = 146450961360
Thus, we can understand that the LCM of 694,764,341,720,648 is 146450961360.
