Given numbers are 785,618,665,618,732
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,618,665,618,732 is 7871719380.
Find LCM of 785,618,665,618,732 with Prime Factorization
| 2 | 785, 618, 665, 618, 732 |
| 3 | 785, 309, 665, 309, 366 |
| 5 | 785, 103, 665, 103, 122 |
| 103 | 157, 103, 133, 103, 122 |
| 157, 1, 133, 1, 122 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 103 x 157 x 1 x 133 x 1 x 122 = 7871719380
Therefore, the lowest common multiple of 785,618,665,618,732 is 7871719380.
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.
785 x 618 x 665 x 618 x 732 = 145941677305200
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.
785 : 1, 5, 157, 785
618 : 1, 2, 3, 6, 103, 206, 309, 618
665 : 1, 5, 7, 19, 35, 95, 133, 665
618 : 1, 2, 3, 6, 103, 206, 309, 618
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,618,665,618,732, is 1.
Now, the common factors can be found like this.
785:5x 157
618:2x 3x 103
665:5x 7x 19
618:2x 3x 103
732:2x 2x 3x 61
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 3x 3x 5x 103 = 18540
Therefore, the value for common factors is 18540.
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 = 145941677305200/(1x18540)
LCM = 145941677305200/18540
LCM = 7871719380
Thus, we can understand that the LCM of 785,618,665,618,732 is 7871719380.
