Given numbers are 110,407,221,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 110,407,221,987 is 887776890.
Find LCM of 110,407,221,987 with Prime Factorization
11 | 110, 407, 221, 987 |
10, 37, 221, 987 |
Multiply the prime numbers at the bottom and the left side.
11 x 10 x 37 x 221 x 987 = 887776890
Therefore, the lowest common multiple of 110,407,221,987 is 887776890.
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.
110 x 407 x 221 x 987 = 9765545790
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.
110 : 1, 2, 5, 10, 11, 22, 55, 110
407 : 1, 11, 37, 407
221 : 1, 13, 17, 221
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 110,407,221,987, is 1.
Now, the common factors can be found like this.
110:2x 5x 11
407:11x 37
221:13x 17
987:3x 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.
11 = 11
Therefore, the value for common factors is 11.
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 = 9765545790/(1x11)
LCM = 9765545790/11
LCM = 887776890
Thus, we can understand that the LCM of 110,407,221,987 is 887776890.
