Given numbers are 629,938,397,494,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,938,397,494,987 is 8157555862638.
Find LCM of 629,938,397,494,987 with Prime Factorization
| 2 | 629, 938, 397, 494, 987 |
| 7 | 629, 469, 397, 247, 987 |
| 629, 67, 397, 247, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 629 x 67 x 397 x 247 x 141 = 8157555862638
Therefore, the lowest common multiple of 629,938,397,494,987 is 8157555862638.
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.
629 x 938 x 397 x 494 x 987 = 114205782076932
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.
629 : 1, 17, 37, 629
938 : 1, 2, 7, 14, 67, 134, 469, 938
397 : 1, 397
494 : 1, 2, 13, 19, 26, 38, 247, 494
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,938,397,494,987, is 1.
Now, the common factors can be found like this.
629:17x 37
938:2x 7x 67
397:397
494:2x 13x 19
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 114205782076932/(1x14)
LCM = 114205782076932/14
LCM = 8157555862638
Thus, we can understand that the LCM of 629,938,397,494,987 is 8157555862638.
