Given numbers are 693,764,968,418,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 693,764,968,418,991 is 219319137576.
Find LCM of 693,764,968,418,991 with Prime Factorization
| 2 | 693, 764, 968, 418, 991 |
| 2 | 693, 382, 484, 209, 991 |
| 11 | 693, 191, 242, 209, 991 |
| 63, 191, 22, 19, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 63 x 191 x 22 x 19 x 991 = 219319137576
Therefore, the lowest common multiple of 693,764,968,418,991 is 219319137576.
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.
693 x 764 x 968 x 418 x 991 = 212300925173568
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
764 : 1, 2, 4, 191, 382, 764
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
418 : 1, 2, 11, 19, 22, 38, 209, 418
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,764,968,418,991, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
764:2x 2x 191
968:2x 2x 2x 11x 11
418:2x 11x 19
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 212300925173568/(1x968)
LCM = 212300925173568/968
LCM = 219319137576
Thus, we can understand that the LCM of 693,764,968,418,991 is 219319137576.
