Given numbers are 978,641,889,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,641,889,635 is 2786561610.
Find LCM of 978,641,889,635 with Prime Factorization
| 127 | 978, 641, 889, 635 |
| 978, 641, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
127 x 978 x 641 x 7 x 5 = 2786561610
Therefore, the lowest common multiple of 978,641,889,635 is 2786561610.
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.
978 x 641 x 889 x 635 = 353893324470
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
641 : 1, 641
889 : 1, 7, 127, 889
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,641,889,635, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
641:641
889:7x 127
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
127 = 127
Therefore, the value for common factors is 127.
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 = 353893324470/(1x127)
LCM = 353893324470/127
LCM = 2786561610
Thus, we can understand that the LCM of 978,641,889,635 is 2786561610.
