Find LCM of 618,840,772,504,618 with Prime Factorization
| 2 | 618, 840, 772, 504, 618 |
| 2 | 309, 420, 386, 252, 309 |
| 2 | 309, 210, 193, 126, 309 |
| 3 | 309, 105, 193, 63, 309 |
| 7 | 103, 35, 193, 21, 103 |
| 103 | 103, 5, 193, 3, 103 |
| 1, 5, 193, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 103 x 1 x 5 x 193 x 3 x 1 = 50095080
Therefore, the lowest common multiple of 618,840,772,504,618 is 50095080.
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.
618 x 840 x 772 x 504 x 618 = 124825718062080
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.
618 : 1, 2, 3, 6, 103, 206, 309, 618
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
772 : 1, 2, 4, 193, 386, 772
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
618 : 1, 2, 3, 6, 103, 206, 309, 618
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 618,840,772,504,618, is 2.
Now, the common factors can be found like this.
618:2x 3x 103
840:2x 2x 2x 3x 5x 7
772:2x 2x 193
504:2x 2x 2x 3x 3x 7
618:2x 3x 103
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 2x 3x 3x 3x 7x 103 = 1245888
Therefore, the value for common factors is 1245888.
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 = 124825718062080/(2x1245888)
LCM = 124825718062080/2491776
LCM = 50095080
Thus, we can understand that the LCM of 618,840,772,504,618 is 50095080.
