Given numbers are 674,695,780,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,695,780,791 is 28901194140.
Find LCM of 674,695,780,791 with Prime Factorization
| 2 | 674, 695, 780, 791 |
| 5 | 337, 695, 390, 791 |
| 337, 139, 78, 791 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 337 x 139 x 78 x 791 = 28901194140
Therefore, the lowest common multiple of 674,695,780,791 is 28901194140.
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.
674 x 695 x 780 x 791 = 289011941400
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.
674 : 1, 2, 337, 674
695 : 1, 5, 139, 695
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,695,780,791, is 1.
Now, the common factors can be found like this.
674:2x 337
695:5x 139
780:2x 2x 3x 5x 13
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 289011941400/(1x10)
LCM = 289011941400/10
LCM = 28901194140
Thus, we can understand that the LCM of 674,695,780,791 is 28901194140.
