Given numbers are 665,749,538,102

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

The LCM of 665,749,538,102 is 1952350890.

Find LCM of 665,749,538,102 with Prime Factorization

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

2 x 7 x 95 x 107 x 269 x 51 = 1952350890

Therefore, the lowest common multiple of 665,749,538,102 is 1952350890.

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.

665 x 749 x 538 x 102 = 27332912460

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

749 : 1, 7, 107, 749

538 : 1, 2, 269, 538

102 : 1, 2, 3, 6, 17, 34, 51, 102

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,749,538,102, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

749:7x 107

538:2x 269

102:2x 3x 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 7 = 14

Therefore, the value for common factors is 14.

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 = 27332912460/(1x14)

LCM = 27332912460/14

LCM = 1952350890

Thus, we can understand that the LCM of 665,749,538,102 is 1952350890.
