Given numbers are 194,143,645,862
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 194,143,645,862 is 7712137290.
Find LCM of 194,143,645,862 with Prime Factorization
| 2 | 194, 143, 645, 862 |
| 97, 143, 645, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 97 x 143 x 645 x 431 = 7712137290
Therefore, the lowest common multiple of 194,143,645,862 is 7712137290.
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.
194 x 143 x 645 x 862 = 15424274580
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.
194 : 1, 2, 97, 194
143 : 1, 11, 13, 143
645 : 1, 3, 5, 15, 43, 129, 215, 645
862 : 1, 2, 431, 862
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,143,645,862, is 1.
Now, the common factors can be found like this.
194:2x 97
143:11x 13
645:3x 5x 43
862:2x 431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 15424274580/(1x2)
LCM = 15424274580/2
LCM = 7712137290
Thus, we can understand that the LCM of 194,143,645,862 is 7712137290.
