Given numbers are 678,427,438,669

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

The LCM of 678,427,438,669 is 4712868174.

Find LCM of 678,427,438,669 with Prime Factorization

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

2 x 3 x 113 x 427 x 73 x 223 = 4712868174

Therefore, the lowest common multiple of 678,427,438,669 is 4712868174.

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.

678 x 427 x 438 x 669 = 84831627132

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

427 : 1, 7, 61, 427

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

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,427,438,669, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

427:7x 61

438:2x 3x 73

669:3x 223

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 84831627132/(1x18)

LCM = 84831627132/18

LCM = 4712868174

Thus, we can understand that the LCM of 678,427,438,669 is 4712868174.
