Given numbers are 721,721,824,613,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,721,824,613,638 is 1127915096.
Find LCM of 721,721,824,613,638 with Prime Factorization
2 | 721, 721, 824, 613, 638 |
7 | 721, 721, 412, 613, 319 |
103 | 103, 103, 412, 613, 319 |
1, 1, 4, 613, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 103 x 1 x 1 x 4 x 613 x 319 = 1127915096
Therefore, the lowest common multiple of 721,721,824,613,638 is 1127915096.
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.
721 x 721 x 824 x 613 x 638 = 167524717548496
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.
721 : 1, 7, 103, 721
721 : 1, 7, 103, 721
824 : 1, 2, 4, 8, 103, 206, 412, 824
613 : 1, 613
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,721,824,613,638, is 1.
Now, the common factors can be found like this.
721:7x 103
721:7x 103
824:2x 2x 2x 103
613:613
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 103x 103 = 148526
Therefore, the value for common factors is 148526.
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 = 167524717548496/(1x148526)
LCM = 167524717548496/148526
LCM = 1127915096
Thus, we can understand that the LCM of 721,721,824,613,638 is 1127915096.
