The LCM of 681,970,262,968,280 is 293179461960.
Find LCM of 681,970,262,968,280 with Prime Factorization
| 2 | 681, 970, 262, 968, 280 |
| 2 | 681, 485, 131, 484, 140 |
| 2 | 681, 485, 131, 242, 70 |
| 5 | 681, 485, 131, 121, 35 |
| 681, 97, 131, 121, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 681 x 97 x 131 x 121 x 7 = 293179461960
Therefore, the lowest common multiple of 681,970,262,968,280 is 293179461960.
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.
681 x 970 x 262 x 968 x 280 = 46908713913600
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.
681 : 1, 3, 227, 681
970 : 1, 2, 5, 10, 97, 194, 485, 970
262 : 1, 2, 131, 262
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,970,262,968,280, is 1.
Now, the common factors can be found like this.
681:3x 227
970:2x 5x 97
262:2x 131
968:2x 2x 2x 11x 11
280:2x 2x 2x 5x 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 2x 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 46908713913600/(1x160)
LCM = 46908713913600/160
LCM = 293179461960
Thus, we can understand that the LCM of 681,970,262,968,280 is 293179461960.
