Given numbers are 786,361,602,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,361,602,721 is 8796977238.
Find LCM of 786,361,602,721 with Prime Factorization
2 | 786, 361, 602, 721 |
7 | 393, 361, 301, 721 |
393, 361, 43, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 393 x 361 x 43 x 103 = 8796977238
Therefore, the lowest common multiple of 786,361,602,721 is 8796977238.
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.
786 x 361 x 602 x 721 = 123157681332
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
361 : 1, 19, 361
602 : 1, 2, 7, 14, 43, 86, 301, 602
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,361,602,721, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
361:19x 19
602:2x 7x 43
721:7x 103
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 = 123157681332/(1x14)
LCM = 123157681332/14
LCM = 8796977238
Thus, we can understand that the LCM of 786,361,602,721 is 8796977238.
