Given numbers are 648,178,283,445

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

The LCM of 648,178,283,445 is 81605880.

Find LCM of 648,178,283,445 with Prime Factorization

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

2 x 89 x 324 x 1 x 283 x 5 = 81605880

Therefore, the lowest common multiple of 648,178,283,445 is 81605880.

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.

648 x 178 x 283 x 445 = 14525846640

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

178 : 1, 2, 89, 178

283 : 1, 283

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,178,283,445, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

178:2x 89

283:283

445:5x 89

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

2x 89 = 178

Therefore, the value for common factors is 178.

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 = 14525846640/(1x178)

LCM = 14525846640/178

LCM = 81605880

Thus, we can understand that the LCM of 648,178,283,445 is 81605880.
