Given numbers are 391,807,724,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,807,724,802 is 91607963988.
Find LCM of 391,807,724,802 with Prime Factorization
2 | 391, 807, 724, 802 |
391, 807, 362, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 391 x 807 x 362 x 401 = 91607963988
Therefore, the lowest common multiple of 391,807,724,802 is 91607963988.
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.
391 x 807 x 724 x 802 = 183215927976
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.
391 : 1, 17, 23, 391
807 : 1, 3, 269, 807
724 : 1, 2, 4, 181, 362, 724
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,807,724,802, is 1.
Now, the common factors can be found like this.
391:17x 23
807:3x 269
724:2x 2x 181
802:2x 401
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 = 183215927976/(1x2)
LCM = 183215927976/2
LCM = 91607963988
Thus, we can understand that the LCM of 391,807,724,802 is 91607963988.
