Given numbers are 619,989,529,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,989,529,215 is 70401965.
Find LCM of 619,989,529,215 with Prime Factorization
| 23 | 619, 989, 529, 215 |
| 43 | 619, 43, 23, 215 |
| 619, 1, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 619 x 1 x 23 x 5 = 70401965
Therefore, the lowest common multiple of 619,989,529,215 is 70401965.
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.
619 x 989 x 529 x 215 = 69627543385
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.
619 : 1, 619
989 : 1, 23, 43, 989
529 : 1, 23, 529
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,989,529,215, is 1.
Now, the common factors can be found like this.
619:619
989:23x 43
529:23x 23
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43 = 989
Therefore, the value for common factors is 989.
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 = 69627543385/(1x989)
LCM = 69627543385/989
LCM = 70401965
Thus, we can understand that the LCM of 619,989,529,215 is 70401965.
