Given numbers are 987,843,762,272,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,843,762,272,140 is 47903373840.
Find LCM of 987,843,762,272,140 with Prime Factorization
| 2 | 987, 843, 762, 272, 140 |
| 2 | 987, 843, 381, 136, 70 |
| 3 | 987, 843, 381, 68, 35 |
| 7 | 329, 281, 127, 68, 35 |
| 47, 281, 127, 68, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 47 x 281 x 127 x 68 x 5 = 47903373840
Therefore, the lowest common multiple of 987,843,762,272,140 is 47903373840.
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 843 x 762 x 272 x 140 = 24143300415360
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
843 : 1, 3, 281, 843
762 : 1, 2, 3, 6, 127, 254, 381, 762
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,843,762,272,140, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
843:3x 281
762:2x 3x 127
272:2x 2x 2x 2x 17
140:2x 2x 5x 7
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 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 24143300415360/(1x504)
LCM = 24143300415360/504
LCM = 47903373840
Thus, we can understand that the LCM of 987,843,762,272,140 is 47903373840.
