Given numbers are 257,381,254,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,381,254,715 is 140021310.
Find LCM of 257,381,254,715 with Prime Factorization
127 | 257, 381, 254, 715 |
257, 3, 2, 715 |
Multiply the prime numbers at the bottom and the left side.
127 x 257 x 3 x 2 x 715 = 140021310
Therefore, the lowest common multiple of 257,381,254,715 is 140021310.
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.
257 x 381 x 254 x 715 = 17782706370
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.
257 : 1, 257
381 : 1, 3, 127, 381
254 : 1, 2, 127, 254
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,381,254,715, is 1.
Now, the common factors can be found like this.
257:257
381:3x 127
254:2x 127
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
127 = 127
Therefore, the value for common factors is 127.
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 = 17782706370/(1x127)
LCM = 17782706370/127
LCM = 140021310
Thus, we can understand that the LCM of 257,381,254,715 is 140021310.
