Given numbers are 791,254,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,254,772 is 77552804.
Find LCM of 791,254,772 with Prime Factorization
| 2 | 791, 254, 772 |
| 791, 127, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 791 x 127 x 386 = 77552804
Therefore, the lowest common multiple of 791,254,772 is 77552804.
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.
791 x 254 x 772 = 155105608
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.
791 : 1, 7, 113, 791
254 : 1, 2, 127, 254
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,254,772, is 1.
Now, the common factors can be found like this.
791:7x 113
254:2x 127
772:2x 2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 155105608/(1x2)
LCM = 155105608/2
LCM = 77552804
Thus, we can understand that the LCM of 791,254,772 is 77552804.
