The LCM of 647,783,693,538 is 20986453026.

Find LCM of 647,783,693,538 with Prime Factorization


3 647, 783, 693, 538
3 647, 261, 231, 538
647, 87, 77, 538

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

3 x 3 x 647 x 87 x 77 x 538 = 20986453026

Therefore, the lowest common multiple of 647,783,693,538 is 20986453026.

LCM Formula to Find Lowest Common Multiple of 647,783,693,538

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 783 x 693 x 538 = 188878077234

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

783 : 1, 3, 9, 27, 29, 87, 261, 783

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,783,693,538, is 1.

Now, the common factors can be found like this.

647:647

783:3x 3x 3x 29

693:3x 3x 7x 11

538:2x 269

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 188878077234/(1x9)

LCM = 188878077234/9

LCM = 20986453026

Thus, we can understand that the LCM of 647,783,693,538 is 20986453026.
