Given numbers are 525,420,839,675,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 525,420,839,675,685 is 2172422700.
Find LCM of 525,420,839,675,685 with Prime Factorization
| 3 | 525, 420, 839, 675, 685 |
| 5 | 175, 140, 839, 225, 685 |
| 5 | 35, 28, 839, 45, 137 |
| 7 | 7, 28, 839, 9, 137 |
| 1, 4, 839, 9, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 7 x 1 x 4 x 839 x 9 x 137 = 2172422700
Therefore, the lowest common multiple of 525,420,839,675,685 is 2172422700.
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.
525 x 420 x 839 x 675 x 685 = 85539143812500
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.
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
839 : 1, 839
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,420,839,675,685, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
420:2x 2x 3x 5x 7
839:839
675:3x 3x 3x 5x 5
685:5x 137
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 5x 5x 5x 5x 7 = 39375
Therefore, the value for common factors is 39375.
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 = 85539143812500/(1x39375)
LCM = 85539143812500/39375
LCM = 2172422700
Thus, we can understand that the LCM of 525,420,839,675,685 is 2172422700.
