The LCM of 773,651,429,990,857 is 1850114456190.
Find LCM of 773,651,429,990,857 with Prime Factorization
| 3 | 773, 651, 429, 990, 857 |
| 11 | 773, 217, 143, 330, 857 |
| 773, 217, 13, 30, 857 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 773 x 217 x 13 x 30 x 857 = 1850114456190
Therefore, the lowest common multiple of 773,651,429,990,857 is 1850114456190.
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.
773 x 651 x 429 x 990 x 857 = 183161331162810
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.
773 : 1, 773
651 : 1, 3, 7, 21, 31, 93, 217, 651
429 : 1, 3, 11, 13, 33, 39, 143, 429
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,651,429,990,857, is 1.
Now, the common factors can be found like this.
773:773
651:3x 7x 31
429:3x 11x 13
990:2x 3x 3x 5x 11
857:857
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 11 = 99
Therefore, the value for common factors is 99.
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 = 183161331162810/(1x99)
LCM = 183161331162810/99
LCM = 1850114456190
Thus, we can understand that the LCM of 773,651,429,990,857 is 1850114456190.
