Given numbers are 423,663,561,262
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,663,561,262 is 269418006.
Find LCM of 423,663,561,262 with Prime Factorization
3 | 423, 663, 561, 262 |
17 | 141, 221, 187, 262 |
141, 13, 11, 262 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 141 x 13 x 11 x 262 = 269418006
Therefore, the lowest common multiple of 423,663,561,262 is 269418006.
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.
423 x 663 x 561 x 262 = 41220954918
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.
423 : 1, 3, 9, 47, 141, 423
663 : 1, 3, 13, 17, 39, 51, 221, 663
561 : 1, 3, 11, 17, 33, 51, 187, 561
262 : 1, 2, 131, 262
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,663,561,262, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
663:3x 13x 17
561:3x 11x 17
262:2x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 41220954918/(1x153)
LCM = 41220954918/153
LCM = 269418006
Thus, we can understand that the LCM of 423,663,561,262 is 269418006.
