Find LCM of 676,990,688,325,764 with Prime Factorization
| 2 | 676, 990, 688, 325, 764 |
| 2 | 338, 495, 344, 325, 382 |
| 5 | 169, 495, 172, 325, 191 |
| 13 | 169, 99, 172, 65, 191 |
| 13, 99, 172, 5, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 13 x 99 x 172 x 5 x 191 = 54964681200
Therefore, the lowest common multiple of 676,990,688,325,764 is 54964681200.
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.
676 x 990 x 688 x 325 x 764 = 114326536896000
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
325 : 1, 5, 13, 25, 65, 325
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,990,688,325,764, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
990:2x 3x 3x 5x 11
688:2x 2x 2x 2x 43
325:5x 5x 13
764:2x 2x 191
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 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 114326536896000/(1x2080)
LCM = 114326536896000/2080
LCM = 54964681200
Thus, we can understand that the LCM of 676,990,688,325,764 is 54964681200.
