Given numbers are 535,407,978,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 535,407,978,665 is 28322963130.
Find LCM of 535,407,978,665 with Prime Factorization
| 5 | 535, 407, 978, 665 |
| 107, 407, 978, 133 |
Multiply the prime numbers at the bottom and the left side.
5 x 107 x 407 x 978 x 133 = 28322963130
Therefore, the lowest common multiple of 535,407,978,665 is 28322963130.
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.
535 x 407 x 978 x 665 = 141614815650
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.
535 : 1, 5, 107, 535
407 : 1, 11, 37, 407
978 : 1, 2, 3, 6, 163, 326, 489, 978
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 535,407,978,665, is 1.
Now, the common factors can be found like this.
535:5x 107
407:11x 37
978:2x 3x 163
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 141614815650/(1x5)
LCM = 141614815650/5
LCM = 28322963130
Thus, we can understand that the LCM of 535,407,978,665 is 28322963130.
