Given numbers are 421,605,692,123,968
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,605,692,123,968 is 43358941560.
Find LCM of 421,605,692,123,968 with Prime Factorization
| 2 | 421, 605, 692, 123, 968 |
| 2 | 421, 605, 346, 123, 484 |
| 11 | 421, 605, 173, 123, 242 |
| 11 | 421, 55, 173, 123, 22 |
| 421, 5, 173, 123, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 11 x 421 x 5 x 173 x 123 x 2 = 43358941560
Therefore, the lowest common multiple of 421,605,692,123,968 is 43358941560.
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.
421 x 605 x 692 x 123 x 968 = 20985727715040
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.
421 : 1, 421
605 : 1, 5, 11, 55, 121, 605
692 : 1, 2, 4, 173, 346, 692
123 : 1, 3, 41, 123
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,605,692,123,968, is 1.
Now, the common factors can be found like this.
421:421
605:5x 11x 11
692:2x 2x 173
123:3x 41
968:2x 2x 2x 11x 11
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 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 20985727715040/(1x484)
LCM = 20985727715040/484
LCM = 43358941560
Thus, we can understand that the LCM of 421,605,692,123,968 is 43358941560.
