Given numbers are 727,278,556,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 727,278,556,404 is 40825412.
Find LCM of 727,278,556,404 with Prime Factorization
| 2 | 727, 278, 556, 404 |
| 2 | 727, 139, 278, 202 |
| 139 | 727, 139, 139, 101 |
| 727, 1, 1, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 727 x 1 x 1 x 101 = 40825412
Therefore, the lowest common multiple of 727,278,556,404 is 40825412.
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.
727 x 278 x 556 x 404 = 45397858144
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.
727 : 1, 727
278 : 1, 2, 139, 278
556 : 1, 2, 4, 139, 278, 556
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,278,556,404, is 1.
Now, the common factors can be found like this.
727:727
278:2x 139
556:2x 2x 139
404:2x 2x 101
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 2x 139 = 1112
Therefore, the value for common factors is 1112.
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 = 45397858144/(1x1112)
LCM = 45397858144/1112
LCM = 40825412
Thus, we can understand that the LCM of 727,278,556,404 is 40825412.
