Given numbers are 742,618,192,759,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 742,618,192,759,989 is 79818091584.
Find LCM of 742,618,192,759,989 with Prime Factorization
| 2 | 742, 618, 192, 759, 989 |
| 3 | 371, 309, 96, 759, 989 |
| 23 | 371, 103, 32, 253, 989 |
| 371, 103, 32, 11, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 371 x 103 x 32 x 11 x 43 = 79818091584
Therefore, the lowest common multiple of 742,618,192,759,989 is 79818091584.
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.
742 x 618 x 192 x 759 x 989 = 66089379831552
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
618 : 1, 2, 3, 6, 103, 206, 309, 618
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
759 : 1, 3, 11, 23, 33, 69, 253, 759
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,618,192,759,989, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
618:2x 3x 103
192:2x 2x 2x 2x 2x 2x 3
759:3x 11x 23
989:23x 43
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 23 = 828
Therefore, the value for common factors is 828.
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 = 66089379831552/(1x828)
LCM = 66089379831552/828
LCM = 79818091584
Thus, we can understand that the LCM of 742,618,192,759,989 is 79818091584.
