Given numbers are 987,247,493,792,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,247,493,792,964 is 7646839848648.
Find LCM of 987,247,493,792,964 with Prime Factorization
| 2 | 987, 247, 493, 792, 964 |
| 2 | 987, 247, 493, 396, 482 |
| 3 | 987, 247, 493, 198, 241 |
| 329, 247, 493, 66, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 329 x 247 x 493 x 66 x 241 = 7646839848648
Therefore, the lowest common multiple of 987,247,493,792,964 is 7646839848648.
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.
987 x 247 x 493 x 792 x 964 = 91762078183776
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
247 : 1, 13, 19, 247
493 : 1, 17, 29, 493
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
964 : 1, 2, 4, 241, 482, 964
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,247,493,792,964, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
247:13x 19
493:17x 29
792:2x 2x 2x 3x 3x 11
964:2x 2x 241
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 = 91762078183776/(1x12)
LCM = 91762078183776/12
LCM = 7646839848648
Thus, we can understand that the LCM of 987,247,493,792,964 is 7646839848648.
