Given numbers are 169,192,550,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,192,550,221 is 151694400.
Find LCM of 169,192,550,221 with Prime Factorization
| 2 | 169, 192, 550, 221 |
| 13 | 169, 96, 275, 221 |
| 13, 96, 275, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 96 x 275 x 17 = 151694400
Therefore, the lowest common multiple of 169,192,550,221 is 151694400.
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.
169 x 192 x 550 x 221 = 3944054400
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.
169 : 1, 13, 169
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,192,550,221, is 1.
Now, the common factors can be found like this.
169:13x 13
192:2x 2x 2x 2x 2x 2x 3
550:2x 5x 5x 11
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.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 3944054400/(1x26)
LCM = 3944054400/26
LCM = 151694400
Thus, we can understand that the LCM of 169,192,550,221 is 151694400.
