Given numbers are 980,987,611,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,987,611,938 is 120354780.
Find LCM of 980,987,611,938 with Prime Factorization
| 2 | 980, 987, 611, 938 |
| 7 | 490, 987, 611, 469 |
| 47 | 70, 141, 611, 67 |
| 70, 3, 13, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 47 x 70 x 3 x 13 x 67 = 120354780
Therefore, the lowest common multiple of 980,987,611,938 is 120354780.
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.
980 x 987 x 611 x 938 = 554354116680
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
987 : 1, 3, 7, 21, 47, 141, 329, 987
611 : 1, 13, 47, 611
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,987,611,938, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
987:3x 7x 47
611:13x 47
938:2x 7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7x 47 = 4606
Therefore, the value for common factors is 4606.
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 = 554354116680/(1x4606)
LCM = 554354116680/4606
LCM = 120354780
Thus, we can understand that the LCM of 980,987,611,938 is 120354780.
