Given numbers are 851,803,715,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,803,715,247 is 843940955.
Find LCM of 851,803,715,247 with Prime Factorization
11 | 851, 803, 715, 247 |
13 | 851, 73, 65, 247 |
851, 73, 5, 19 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 851 x 73 x 5 x 19 = 843940955
Therefore, the lowest common multiple of 851,803,715,247 is 843940955.
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.
851 x 803 x 715 x 247 = 120683556565
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.
851 : 1, 23, 37, 851
803 : 1, 11, 73, 803
715 : 1, 5, 11, 13, 55, 65, 143, 715
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,803,715,247, is 1.
Now, the common factors can be found like this.
851:23x 37
803:11x 73
715:5x 11x 13
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 120683556565/(1x143)
LCM = 120683556565/143
LCM = 843940955
Thus, we can understand that the LCM of 851,803,715,247 is 843940955.
