The LCM of 456,618,903,693 is 466533144.
Find LCM of 456,618,903,693 with Prime Factorization
| 2 | 456, 618, 903, 693 |
| 3 | 228, 309, 903, 693 |
| 7 | 76, 103, 301, 231 |
| 76, 103, 43, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 76 x 103 x 43 x 33 = 466533144
Therefore, the lowest common multiple of 456,618,903,693 is 466533144.
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 618 x 903 x 693 = 176349528432
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
618 : 1, 2, 3, 6, 103, 206, 309, 618
903 : 1, 3, 7, 21, 43, 129, 301, 903
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,618,903,693, is 3.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
618:2x 3x 103
903:3x 7x 43
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 176349528432/(3x126)
LCM = 176349528432/378
LCM = 466533144
Thus, we can understand that the LCM of 456,618,903,693 is 466533144.
