The LCM of 456,360,894,691 is 704239560.
Find LCM of 456,360,894,691 with Prime Factorization
| 2 | 456, 360, 894, 691 |
| 2 | 228, 180, 447, 691 |
| 2 | 114, 90, 447, 691 |
| 3 | 57, 45, 447, 691 |
| 19, 15, 149, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 15 x 149 x 691 = 704239560
Therefore, the lowest common multiple of 456,360,894,691 is 704239560.
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.
456 x 360 x 894 x 691 = 101410496640
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
894 : 1, 2, 3, 6, 149, 298, 447, 894
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,360,894,691, is 1.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
360:2x 2x 2x 3x 3x 5
894:2x 3x 149
691:691
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 101410496640/(1x144)
LCM = 101410496640/144
LCM = 704239560
Thus, we can understand that the LCM of 456,360,894,691 is 704239560.
