Given numbers are 477,690,661,742,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 477,690,661,742,794 is 201528383490.
Find LCM of 477,690,661,742,794 with Prime Factorization
| 2 | 477, 690, 661, 742, 794 |
| 3 | 477, 345, 661, 371, 397 |
| 53 | 159, 115, 661, 371, 397 |
| 3, 115, 661, 7, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 53 x 3 x 115 x 661 x 7 x 397 = 201528383490
Therefore, the lowest common multiple of 477,690,661,742,794 is 201528383490.
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.
477 x 690 x 661 x 742 x 794 = 128172051899640
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.
477 : 1, 3, 9, 53, 159, 477
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
661 : 1, 661
742 : 1, 2, 7, 14, 53, 106, 371, 742
794 : 1, 2, 397, 794
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 477,690,661,742,794, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
690:2x 3x 5x 23
661:661
742:2x 7x 53
794:2x 397
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 53 = 636
Therefore, the value for common factors is 636.
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 = 128172051899640/(1x636)
LCM = 128172051899640/636
LCM = 201528383490
Thus, we can understand that the LCM of 477,690,661,742,794 is 201528383490.
