Find LCM of 685,665,630,536,954 with Prime Factorization
| 2 | 685, 665, 630, 536, 954 |
| 3 | 685, 665, 315, 268, 477 |
| 3 | 685, 665, 105, 268, 159 |
| 5 | 685, 665, 35, 268, 53 |
| 7 | 137, 133, 7, 268, 53 |
| 137, 19, 1, 268, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 137 x 19 x 1 x 268 x 53 = 23292997560
Therefore, the lowest common multiple of 685,665,630,536,954 is 23292997560.
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.
685 x 665 x 630 x 536 x 954 = 146745884628000
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.
685 : 1, 5, 137, 685
665 : 1, 5, 7, 19, 35, 95, 133, 665
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
536 : 1, 2, 4, 8, 67, 134, 268, 536
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,665,630,536,954, is 1.
Now, the common factors can be found like this.
685:5x 137
665:5x 7x 19
630:2x 3x 3x 5x 7
536:2x 2x 2x 67
954:2x 3x 3x 53
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 5x 5x 7 = 6300
Therefore, the value for common factors is 6300.
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 = 146745884628000/(1x6300)
LCM = 146745884628000/6300
LCM = 23292997560
Thus, we can understand that the LCM of 685,665,630,536,954 is 23292997560.
