Given numbers are 427,257,438,949

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 427,257,438,949 is 624853866.

Find LCM of 427,257,438,949 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

73 x 427 x 257 x 6 x 13 = 624853866

Therefore, the lowest common multiple of 427,257,438,949 is 624853866.

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.

427 x 257 x 438 x 949 = 45614332218

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.

427 : 1, 7, 61, 427

257 : 1, 257

438 : 1, 2, 3, 6, 73, 146, 219, 438

949 : 1, 13, 73, 949

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,257,438,949, is 1.

Now, the common factors can be found like this.

427:7x 61

257:257

438:2x 3x 73

949:13x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

73 = 73

Therefore, the value for common factors is 73.

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 = 45614332218/(1x73)

LCM = 45614332218/73

LCM = 624853866

Thus, we can understand that the LCM of 427,257,438,949 is 624853866.
