Given numbers are 672,447,531,445,785

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

The LCM of 672,447,531,445,785 is 1238193361440.

Find LCM of 672,447,531,445,785 with Prime Factorization

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

3 x 5 x 224 x 149 x 177 x 89 x 157 = 1238193361440

Therefore, the lowest common multiple of 672,447,531,445,785 is 1238193361440.

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.

672 x 447 x 531 x 445 x 785 = 55718701264800

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

447 : 1, 3, 149, 447

531 : 1, 3, 9, 59, 177, 531

445 : 1, 5, 89, 445

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,447,531,445,785, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

447:3x 149

531:3x 3x 59

445:5x 89

785:5x 157

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

3x 3x 5 = 45

Therefore, the value for common factors is 45.

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 = 55718701264800/(1x45)

LCM = 55718701264800/45

LCM = 1238193361440

Thus, we can understand that the LCM of 672,447,531,445,785 is 1238193361440.
