Given numbers are 103,721,368,538,207

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

The LCM of 103,721,368,538,207 is 642359088.

Find LCM of 103,721,368,538,207 with Prime Factorization

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

2 x 23 x 103 x 1 x 7 x 8 x 269 x 9 = 642359088

Therefore, the lowest common multiple of 103,721,368,538,207 is 642359088.

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.

103 x 721 x 368 x 538 x 207 = 3043497358944

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.

103 : 1, 103

721 : 1, 7, 103, 721

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

538 : 1, 2, 269, 538

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,721,368,538,207, is 1.

Now, the common factors can be found like this.

103:103

721:7x 103

368:2x 2x 2x 2x 23

538:2x 269

207:3x 3x 23

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

2x 23x 103 = 4738

Therefore, the value for common factors is 4738.

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 = 3043497358944/(1x4738)

LCM = 3043497358944/4738

LCM = 642359088

Thus, we can understand that the LCM of 103,721,368,538,207 is 642359088.
