Find LCM of 783,618,901,493,765 with Prime Factorization
| 3 | 783, 618, 901, 493, 765 |
| 3 | 261, 206, 901, 493, 255 |
| 17 | 87, 206, 901, 493, 85 |
| 29 | 87, 206, 53, 29, 5 |
| 3, 206, 53, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 29 x 3 x 206 x 53 x 1 x 5 = 726647490
Therefore, the lowest common multiple of 783,618,901,493,765 is 726647490.
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.
783 x 618 x 901 x 493 x 765 = 164430880569630
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
618 : 1, 2, 3, 6, 103, 206, 309, 618
901 : 1, 17, 53, 901
493 : 1, 17, 29, 493
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,618,901,493,765, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
618:2x 3x 103
901:17x 53
493:17x 29
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17x 17x 29 = 226287
Therefore, the value for common factors is 226287.
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 = 164430880569630/(1x226287)
LCM = 164430880569630/226287
LCM = 726647490
Thus, we can understand that the LCM of 783,618,901,493,765 is 726647490.
