Given numbers are 380,456,353,431,251
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,456,353,431,251 is 87068396040.
Find LCM of 380,456,353,431,251 with Prime Factorization
2 | 380, 456, 353, 431, 251 |
2 | 190, 228, 353, 431, 251 |
19 | 95, 114, 353, 431, 251 |
5, 6, 353, 431, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 5 x 6 x 353 x 431 x 251 = 87068396040
Therefore, the lowest common multiple of 380,456,353,431,251 is 87068396040.
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.
380 x 456 x 353 x 431 x 251 = 6617198099040
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
353 : 1, 353
431 : 1, 431
251 : 1, 251
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,456,353,431,251, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
456:2x 2x 2x 3x 19
353:353
431:431
251:251
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 19 = 76
Therefore, the value for common factors is 76.
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 = 6617198099040/(1x76)
LCM = 6617198099040/76
LCM = 87068396040
Thus, we can understand that the LCM of 380,456,353,431,251 is 87068396040.
