Given numbers are 769,634,322,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,634,322,658 is 3689260582.
Find LCM of 769,634,322,658 with Prime Factorization
| 2 | 769, 634, 322, 658 |
| 7 | 769, 317, 161, 329 |
| 769, 317, 23, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 769 x 317 x 23 x 47 = 3689260582
Therefore, the lowest common multiple of 769,634,322,658 is 3689260582.
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.
769 x 634 x 322 x 658 = 103299296296
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.
769 : 1, 769
634 : 1, 2, 317, 634
322 : 1, 2, 7, 14, 23, 46, 161, 322
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,634,322,658, is 1.
Now, the common factors can be found like this.
769:769
634:2x 317
322:2x 7x 23
658:2x 7x 47
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 7 = 28
Therefore, the value for common factors is 28.
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 = 103299296296/(1x28)
LCM = 103299296296/28
LCM = 3689260582
Thus, we can understand that the LCM of 769,634,322,658 is 3689260582.
