The LCM of 945,791,676,565 is 72186660.
Find LCM of 945,791,676,565 with Prime Factorization
| 5 | 945, 791, 676, 565 |
| 7 | 189, 791, 676, 113 |
| 113 | 27, 113, 676, 113 |
| 27, 1, 676, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 113 x 27 x 1 x 676 x 1 = 72186660
Therefore, the lowest common multiple of 945,791,676,565 is 72186660.
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.
945 x 791 x 676 x 565 = 285498240300
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
791 : 1, 7, 113, 791
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
565 : 1, 5, 113, 565
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,791,676,565, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
791:7x 113
676:2x 2x 13x 13
565:5x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 113 = 3955
Therefore, the value for common factors is 3955.
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 = 285498240300/(1x3955)
LCM = 285498240300/3955
LCM = 72186660
Thus, we can understand that the LCM of 945,791,676,565 is 72186660.
