Given numbers are 247,715,470,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,715,470,189 is 241351110.
Find LCM of 247,715,470,189 with Prime Factorization
5 | 247, 715, 470, 189 |
13 | 247, 143, 94, 189 |
19, 11, 94, 189 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 19 x 11 x 94 x 189 = 241351110
Therefore, the lowest common multiple of 247,715,470,189 is 241351110.
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.
247 x 715 x 470 x 189 = 15687822150
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.
247 : 1, 13, 19, 247
715 : 1, 5, 11, 13, 55, 65, 143, 715
470 : 1, 2, 5, 10, 47, 94, 235, 470
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,715,470,189, is 1.
Now, the common factors can be found like this.
247:13x 19
715:5x 11x 13
470:2x 5x 47
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13 = 65
Therefore, the value for common factors is 65.
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 = 15687822150/(1x65)
LCM = 15687822150/65
LCM = 241351110
Thus, we can understand that the LCM of 247,715,470,189 is 241351110.
