Given numbers are 713,640,722,961,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 713,640,722,961,321 is 1639243355520.
Find LCM of 713,640,722,961,321 with Prime Factorization
| 2 | 713, 640, 722, 961, 321 |
| 31 | 713, 320, 361, 961, 321 |
| 23, 320, 361, 31, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 23 x 320 x 361 x 31 x 321 = 1639243355520
Therefore, the lowest common multiple of 713,640,722,961,321 is 1639243355520.
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.
713 x 640 x 722 x 961 x 321 = 101633088042240
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.
713 : 1, 23, 31, 713
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
722 : 1, 2, 19, 38, 361, 722
961 : 1, 31, 961
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,640,722,961,321, is 1.
Now, the common factors can be found like this.
713:23x 31
640:2x 2x 2x 2x 2x 2x 2x 5
722:2x 19x 19
961:31x 31
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 101633088042240/(1x62)
LCM = 101633088042240/62
LCM = 1639243355520
Thus, we can understand that the LCM of 713,640,722,961,321 is 1639243355520.
