Given numbers are 525,700,494,821,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 525,700,494,821,245 is 2980968900.
Find LCM of 525,700,494,821,245 with Prime Factorization
| 2 | 525, 700, 494, 821, 245 |
| 5 | 525, 350, 247, 821, 245 |
| 5 | 105, 70, 247, 821, 49 |
| 7 | 21, 14, 247, 821, 49 |
| 3, 2, 247, 821, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 7 x 3 x 2 x 247 x 821 x 7 = 2980968900
Therefore, the lowest common multiple of 525,700,494,821,245 is 2980968900.
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 700 x 494 x 821 x 245 = 36516869025000
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
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
494 : 1, 2, 13, 19, 26, 38, 247, 494
821 : 1, 821
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 525,700,494,821,245, is 1.
Now, the common factors can be found like this.
525:3x 5x 5x 7
700:2x 2x 5x 5x 7
494:2x 13x 19
821:821
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 7x 7 = 12250
Therefore, the value for common factors is 12250.
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 = 36516869025000/(1x12250)
LCM = 36516869025000/12250
LCM = 2980968900
Thus, we can understand that the LCM of 525,700,494,821,245 is 2980968900.
