Given numbers are 1,156,923,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,156,923,221 is 188292.
Find LCM of 1,156,923,221 with Prime Factorization
13 | 1, 156, 923, 221 |
1, 12, 71, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 1 x 12 x 71 x 17 = 188292
Therefore, the lowest common multiple of 1,156,923,221 is 188292.
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.
1 x 156 x 923 x 221 = 31821348
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.
1 : 1
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
923 : 1, 13, 71, 923
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,156,923,221, is 1.
Now, the common factors can be found like this.
1:
156:2x 2x 3x 13
923:13x 71
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 31821348/(1x169)
LCM = 31821348/169
LCM = 188292
Thus, we can understand that the LCM of 1,156,923,221 is 188292.
