Given numbers are 551,580,789,970
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,580,789,970 is 843393660.
Find LCM of 551,580,789,970 with Prime Factorization
2 | 551, 580, 789, 970 |
5 | 551, 290, 789, 485 |
29 | 551, 58, 789, 97 |
19, 2, 789, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 19 x 2 x 789 x 97 = 843393660
Therefore, the lowest common multiple of 551,580,789,970 is 843393660.
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.
551 x 580 x 789 x 970 = 244584161400
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.
551 : 1, 19, 29, 551
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
789 : 1, 3, 263, 789
970 : 1, 2, 5, 10, 97, 194, 485, 970
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,580,789,970, is 1.
Now, the common factors can be found like this.
551:19x 29
580:2x 2x 5x 29
789:3x 263
970:2x 5x 97
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 29 = 290
Therefore, the value for common factors is 290.
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 = 244584161400/(1x290)
LCM = 244584161400/290
LCM = 843393660
Thus, we can understand that the LCM of 551,580,789,970 is 843393660.
