Given numbers are 978,611,262,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,611,262,655 is 391400490.
Find LCM of 978,611,262,655 with Prime Factorization
| 2 | 978, 611, 262, 655 |
| 131 | 489, 611, 131, 655 |
| 489, 611, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 131 x 489 x 611 x 1 x 5 = 391400490
Therefore, the lowest common multiple of 978,611,262,655 is 391400490.
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 611 x 262 x 655 = 102546928380
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
611 : 1, 13, 47, 611
262 : 1, 2, 131, 262
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,611,262,655, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
611:13x 47
262:2x 131
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 131 = 262
Therefore, the value for common factors is 262.
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 = 102546928380/(1x262)
LCM = 102546928380/262
LCM = 391400490
Thus, we can understand that the LCM of 978,611,262,655 is 391400490.
