Given numbers are 791,737,621,705,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,737,621,705,660 is 340301156580.
Find LCM of 791,737,621,705,660 with Prime Factorization
| 3 | 791, 737, 621, 705, 660 |
| 5 | 791, 737, 207, 235, 220 |
| 11 | 791, 737, 207, 47, 44 |
| 791, 67, 207, 47, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 791 x 67 x 207 x 47 x 4 = 340301156580
Therefore, the lowest common multiple of 791,737,621,705,660 is 340301156580.
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.
791 x 737 x 621 x 705 x 660 = 168449072507100
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.
791 : 1, 7, 113, 791
737 : 1, 11, 67, 737
621 : 1, 3, 9, 23, 27, 69, 207, 621
705 : 1, 3, 5, 15, 47, 141, 235, 705
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,737,621,705,660, is 1.
Now, the common factors can be found like this.
791:7x 113
737:11x 67
621:3x 3x 3x 23
705:3x 5x 47
660:2x 2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 11 = 495
Therefore, the value for common factors is 495.
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 = 168449072507100/(1x495)
LCM = 168449072507100/495
LCM = 340301156580
Thus, we can understand that the LCM of 791,737,621,705,660 is 340301156580.
