Given numbers are 647,685,137,744

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

The LCM of 647,685,137,744 is 329737080.

Find LCM of 647,685,137,744 with Prime Factorization

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

137 x 647 x 5 x 1 x 744 = 329737080

Therefore, the lowest common multiple of 647,685,137,744 is 329737080.

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.

647 x 685 x 137 x 744 = 45173979960

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.

647 : 1, 647

685 : 1, 5, 137, 685

137 : 1, 137

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,685,137,744, is 1.

Now, the common factors can be found like this.

647:647

685:5x 137

137:137

744:2x 2x 2x 3x 31

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

137 = 137

Therefore, the value for common factors is 137.

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 = 45173979960/(1x137)

LCM = 45173979960/137

LCM = 329737080

Thus, we can understand that the LCM of 647,685,137,744 is 329737080.
