Given numbers are 221,988,711,425
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,988,711,425 is 298548900.
Find LCM of 221,988,711,425 with Prime Factorization
13 | 221, 988, 711, 425 |
17 | 17, 76, 711, 425 |
1, 76, 711, 25 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 1 x 76 x 711 x 25 = 298548900
Therefore, the lowest common multiple of 221,988,711,425 is 298548900.
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.
221 x 988 x 711 x 425 = 65979306900
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.
221 : 1, 13, 17, 221
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
711 : 1, 3, 9, 79, 237, 711
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,988,711,425, is 1.
Now, the common factors can be found like this.
221:13x 17
988:2x 2x 13x 19
711:3x 3x 79
425:5x 5x 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 17 = 221
Therefore, the value for common factors is 221.
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 = 65979306900/(1x221)
LCM = 65979306900/221
LCM = 298548900
Thus, we can understand that the LCM of 221,988,711,425 is 298548900.
