Given numbers are 272,142,923,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,142,923,779 is 195572624.
Find LCM of 272,142,923,779 with Prime Factorization
| 2 | 272, 142, 923, 779 |
| 71 | 136, 71, 923, 779 |
| 136, 1, 13, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 136 x 1 x 13 x 779 = 195572624
Therefore, the lowest common multiple of 272,142,923,779 is 195572624.
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.
272 x 142 x 923 x 779 = 27771312608
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
142 : 1, 2, 71, 142
923 : 1, 13, 71, 923
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,142,923,779, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
142:2x 71
923:13x 71
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 27771312608/(1x142)
LCM = 27771312608/142
LCM = 195572624
Thus, we can understand that the LCM of 272,142,923,779 is 195572624.
