657, 7, 1, 11, 1

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

2 x 2 x 2 x 2 x 17 x 61 x 657 x 7 x 1 x 11 x 1 = 839372688

Therefore, the lowest common multiple of 657,427,976,748,272 is 839372688.

LCM Formula to Find Lowest Common Multiple of 657,427,976,748,272

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.

657 x 427 x 976 x 748 x 272 = 55707486557184

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.

657 : 1, 3, 9, 73, 219, 657

427 : 1, 7, 61, 427

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,427,976,748,272, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

427:7x 61

976:2x 2x 2x 2x 61

748:2x 2x 11x 17

272:2x 2x 2x 2x 17

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

2x 2x 2x 2x 2x 2x 17x 61 = 66368

Therefore, the value for common factors is 66368.

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 = 55707486557184/(1x66368)

LCM = 55707486557184/66368

LCM = 839372688

Thus, we can understand that the LCM of 657,427,976,748,272 is 839372688.
