Given numbers are 248,407,678,747

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

The LCM of 248,407,678,747 is 8520108696.

Find LCM of 248,407,678,747 with Prime Factorization

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

2 x 3 x 124 x 407 x 113 x 249 = 8520108696

Therefore, the lowest common multiple of 248,407,678,747 is 8520108696.

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.

248 x 407 x 678 x 747 = 51120652176

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.

248 : 1, 2, 4, 8, 31, 62, 124, 248

407 : 1, 11, 37, 407

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

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,407,678,747, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

407:11x 37

678:2x 3x 113

747:3x 3x 83

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 51120652176/(1x6)

LCM = 51120652176/6

LCM = 8520108696

Thus, we can understand that the LCM of 248,407,678,747 is 8520108696.
