Given numbers are 532,973,751,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 532,973,751,721 is 5720099644.
Find LCM of 532,973,751,721 with Prime Factorization
| 7 | 532, 973, 751, 721 |
| 76, 139, 751, 103 |
Multiply the prime numbers at the bottom and the left side.
7 x 76 x 139 x 751 x 103 = 5720099644
Therefore, the lowest common multiple of 532,973,751,721 is 5720099644.
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.
532 x 973 x 751 x 721 = 280284882556
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.
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
973 : 1, 7, 139, 973
751 : 1, 751
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 532,973,751,721, is 1.
Now, the common factors can be found like this.
532:2x 2x 7x 19
973:7x 139
751:751
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.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 280284882556/(1x49)
LCM = 280284882556/49
LCM = 5720099644
Thus, we can understand that the LCM of 532,973,751,721 is 5720099644.
