Given numbers are 630,978,764,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,978,764,341 is 13376604780.
Find LCM of 630,978,764,341 with Prime Factorization
| 2 | 630, 978, 764, 341 |
| 3 | 315, 489, 382, 341 |
| 105, 163, 382, 341 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 105 x 163 x 382 x 341 = 13376604780
Therefore, the lowest common multiple of 630,978,764,341 is 13376604780.
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.
630 x 978 x 764 x 341 = 160519257360
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
978 : 1, 2, 3, 6, 163, 326, 489, 978
764 : 1, 2, 4, 191, 382, 764
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,978,764,341, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
978:2x 3x 163
764:2x 2x 191
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 160519257360/(1x12)
LCM = 160519257360/12
LCM = 13376604780
Thus, we can understand that the LCM of 630,978,764,341 is 13376604780.
