Given numbers are 829,140,470,320,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,140,470,320,242 is 10560531520.
Find LCM of 829,140,470,320,242 with Prime Factorization
| 2 | 829, 140, 470, 320, 242 |
| 2 | 829, 70, 235, 160, 121 |
| 5 | 829, 35, 235, 80, 121 |
| 829, 7, 47, 16, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 829 x 7 x 47 x 16 x 121 = 10560531520
Therefore, the lowest common multiple of 829,140,470,320,242 is 10560531520.
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.
829 x 140 x 470 x 320 x 242 = 4224212608000
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.
829 : 1, 829
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
470 : 1, 2, 5, 10, 47, 94, 235, 470
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,140,470,320,242, is 1.
Now, the common factors can be found like this.
829:829
140:2x 2x 5x 7
470:2x 5x 47
320:2x 2x 2x 2x 2x 2x 5
242:2x 11x 11
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 2x 2x 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 4224212608000/(1x400)
LCM = 4224212608000/400
LCM = 10560531520
Thus, we can understand that the LCM of 829,140,470,320,242 is 10560531520.
