Given numbers are 556,940,722,930,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,940,722,930,641 is 2811841483380.
Find LCM of 556,940,722,930,641 with Prime Factorization
| 2 | 556, 940, 722, 930, 641 |
| 2 | 278, 470, 361, 465, 641 |
| 5 | 139, 235, 361, 465, 641 |
| 139, 47, 361, 93, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 139 x 47 x 361 x 93 x 641 = 2811841483380
Therefore, the lowest common multiple of 556,940,722,930,641 is 2811841483380.
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.
556 x 940 x 722 x 930 x 641 = 224947318670400
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.
556 : 1, 2, 4, 139, 278, 556
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
722 : 1, 2, 19, 38, 361, 722
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,940,722,930,641, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
940:2x 2x 5x 47
722:2x 19x 19
930:2x 3x 5x 31
641:641
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 224947318670400/(1x80)
LCM = 224947318670400/80
LCM = 2811841483380
Thus, we can understand that the LCM of 556,940,722,930,641 is 2811841483380.
