Find LCM of 281,764,679,420,894 with Prime Factorization
| 2 | 281, 764, 679, 420, 894 |
| 2 | 281, 382, 679, 210, 447 |
| 3 | 281, 191, 679, 105, 447 |
| 7 | 281, 191, 679, 35, 149 |
| 281, 191, 97, 5, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 281 x 191 x 97 x 5 x 149 = 325796924460
Therefore, the lowest common multiple of 281,764,679,420,894 is 325796924460.
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.
281 x 764 x 679 x 420 x 894 = 54733883309280
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.
281 : 1, 281
764 : 1, 2, 4, 191, 382, 764
679 : 1, 7, 97, 679
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,764,679,420,894, is 1.
Now, the common factors can be found like this.
281:281
764:2x 2x 191
679:7x 97
420:2x 2x 3x 5x 7
894:2x 3x 149
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 54733883309280/(1x168)
LCM = 54733883309280/168
LCM = 325796924460
Thus, we can understand that the LCM of 281,764,679,420,894 is 325796924460.
