Given numbers are 635,438,292,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,438,292,918 is 85107780.
Find LCM of 635,438,292,918 with Prime Factorization
| 2 | 635, 438, 292, 918 |
| 3 | 635, 219, 146, 459 |
| 73 | 635, 73, 146, 153 |
| 635, 1, 2, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 635 x 1 x 2 x 153 = 85107780
Therefore, the lowest common multiple of 635,438,292,918 is 85107780.
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.
635 x 438 x 292 x 918 = 74554415280
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.
635 : 1, 5, 127, 635
438 : 1, 2, 3, 6, 73, 146, 219, 438
292 : 1, 2, 4, 73, 146, 292
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,438,292,918, is 1.
Now, the common factors can be found like this.
635:5x 127
438:2x 3x 73
292:2x 2x 73
918:2x 3x 3x 3x 17
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 3x 73 = 876
Therefore, the value for common factors is 876.
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 = 74554415280/(1x876)
LCM = 74554415280/876
LCM = 85107780
Thus, we can understand that the LCM of 635,438,292,918 is 85107780.
