Given numbers are 989,514,427,257,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,514,427,257,802 is 87042560542.
Find LCM of 989,514,427,257,802 with Prime Factorization
| 2 | 989, 514, 427, 257, 802 |
| 257 | 989, 257, 427, 257, 401 |
| 989, 1, 427, 1, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 257 x 989 x 1 x 427 x 1 x 401 = 87042560542
Therefore, the lowest common multiple of 989,514,427,257,802 is 87042560542.
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.
989 x 514 x 427 x 257 x 802 = 44739876118588
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.
989 : 1, 23, 43, 989
514 : 1, 2, 257, 514
427 : 1, 7, 61, 427
257 : 1, 257
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,514,427,257,802, is 1.
Now, the common factors can be found like this.
989:23x 43
514:2x 257
427:7x 61
257:257
802:2x 401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 257 = 514
Therefore, the value for common factors is 514.
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 = 44739876118588/(1x514)
LCM = 44739876118588/514
LCM = 87042560542
Thus, we can understand that the LCM of 989,514,427,257,802 is 87042560542.
