Given numbers are 197,320,254,394,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,320,254,394,762 is 24018240.
Find LCM of 197,320,254,394,762 with Prime Factorization
| 2 | 197, 320, 254, 394, 762 |
| 127 | 197, 160, 127, 197, 381 |
| 197 | 197, 160, 1, 197, 3 |
| 1, 160, 1, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 127 x 197 x 1 x 160 x 1 x 1 x 3 = 24018240
Therefore, the lowest common multiple of 197,320,254,394,762 is 24018240.
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.
197 x 320 x 254 x 394 x 762 = 4807298772480
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.
197 : 1, 197
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
254 : 1, 2, 127, 254
394 : 1, 2, 197, 394
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,320,254,394,762, is 1.
Now, the common factors can be found like this.
197:197
320:2x 2x 2x 2x 2x 2x 5
254:2x 127
394:2x 197
762:2x 3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 127x 197 = 200152
Therefore, the value for common factors is 200152.
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 = 4807298772480/(1x200152)
LCM = 4807298772480/200152
LCM = 24018240
Thus, we can understand that the LCM of 197,320,254,394,762 is 24018240.
