Given numbers are 658,722,304,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,722,304,561 is 1066070544.
Find LCM of 658,722,304,561 with Prime Factorization
2 | 658, 722, 304, 561 |
19 | 329, 361, 152, 561 |
329, 19, 8, 561 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 329 x 19 x 8 x 561 = 1066070544
Therefore, the lowest common multiple of 658,722,304,561 is 1066070544.
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.
658 x 722 x 304 x 561 = 81021361344
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
722 : 1, 2, 19, 38, 361, 722
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,722,304,561, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
722:2x 19x 19
304:2x 2x 2x 2x 19
561:3x 11x 17
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 19 = 76
Therefore, the value for common factors is 76.
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 = 81021361344/(1x76)
LCM = 81021361344/76
LCM = 1066070544
Thus, we can understand that the LCM of 658,722,304,561 is 1066070544.
