Given numbers are 722,978,853,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,978,853,869 is 261706713906.
Find LCM of 722,978,853,869 with Prime Factorization
| 2 | 722, 978, 853, 869 |
| 361, 489, 853, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 361 x 489 x 853 x 869 = 261706713906
Therefore, the lowest common multiple of 722,978,853,869 is 261706713906.
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.
722 x 978 x 853 x 869 = 523413427812
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.
722 : 1, 2, 19, 38, 361, 722
978 : 1, 2, 3, 6, 163, 326, 489, 978
853 : 1, 853
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,978,853,869, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
978:2x 3x 163
853:853
869:11x 79
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 = 523413427812/(1x2)
LCM = 523413427812/2
LCM = 261706713906
Thus, we can understand that the LCM of 722,978,853,869 is 261706713906.
