Given numbers are 762,449,669,635
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,449,669,635 is 381483870.
Find LCM of 762,449,669,635 with Prime Factorization
| 3 | 762, 449, 669, 635 |
| 127 | 254, 449, 223, 635 |
| 2, 449, 223, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 2 x 449 x 223 x 5 = 381483870
Therefore, the lowest common multiple of 762,449,669,635 is 381483870.
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.
762 x 449 x 669 x 635 = 145345354470
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
449 : 1, 449
669 : 1, 3, 223, 669
635 : 1, 5, 127, 635
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,449,669,635, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
449:449
669:3x 223
635:5x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 127 = 381
Therefore, the value for common factors is 381.
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 = 145345354470/(1x381)
LCM = 145345354470/381
LCM = 381483870
Thus, we can understand that the LCM of 762,449,669,635 is 381483870.
