Given numbers are 969,722,279,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,722,279,645 is 736255890.
Find LCM of 969,722,279,645 with Prime Factorization
| 3 | 969, 722, 279, 645 |
| 19 | 323, 722, 93, 215 |
| 17, 38, 93, 215 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 17 x 38 x 93 x 215 = 736255890
Therefore, the lowest common multiple of 969,722,279,645 is 736255890.
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.
969 x 722 x 279 x 645 = 125899757190
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
722 : 1, 2, 19, 38, 361, 722
279 : 1, 3, 9, 31, 93, 279
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,722,279,645, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
722:2x 19x 19
279:3x 3x 31
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 125899757190/(1x171)
LCM = 125899757190/171
LCM = 736255890
Thus, we can understand that the LCM of 969,722,279,645 is 736255890.
