Given numbers are 389,505,542,994,202
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,505,542,994,202 is 52917175430.
Find LCM of 389,505,542,994,202 with Prime Factorization
| 2 | 389, 505, 542, 994, 202 |
| 101 | 389, 505, 271, 497, 101 |
| 389, 5, 271, 497, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 101 x 389 x 5 x 271 x 497 x 1 = 52917175430
Therefore, the lowest common multiple of 389,505,542,994,202 is 52917175430.
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.
389 x 505 x 542 x 994 x 202 = 21378538873720
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.
389 : 1, 389
505 : 1, 5, 101, 505
542 : 1, 2, 271, 542
994 : 1, 2, 7, 14, 71, 142, 497, 994
202 : 1, 2, 101, 202
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,505,542,994,202, is 1.
Now, the common factors can be found like this.
389:389
505:5x 101
542:2x 271
994:2x 7x 71
202:2x 101
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 101 = 404
Therefore, the value for common factors is 404.
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 = 21378538873720/(1x404)
LCM = 21378538873720/404
LCM = 52917175430
Thus, we can understand that the LCM of 389,505,542,994,202 is 52917175430.
