Given numbers are 672,781,221,362,977

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

The LCM of 672,781,221,362,977 is 20510947320864.

Find LCM of 672,781,221,362,977 with Prime Factorization

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

2 x 336 x 781 x 221 x 181 x 977 = 20510947320864

Therefore, the lowest common multiple of 672,781,221,362,977 is 20510947320864.

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 781 x 221 x 362 x 977 = 41021894641728

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

781 : 1, 11, 71, 781

221 : 1, 13, 17, 221

362 : 1, 2, 181, 362

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,781,221,362,977, is 1.

Now, the common factors can be found like this.

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

781:11x 71

221:13x 17

362:2x 181

977:977

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

2 = 2

Therefore, the value for common factors is 2.

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 = 41021894641728/(1x2)

LCM = 41021894641728/2

LCM = 20510947320864

Thus, we can understand that the LCM of 672,781,221,362,977 is 20510947320864.
