Given numbers are 665,409,273,782

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

The LCM of 665,409,273,782 is 8294998530.

Find LCM of 665,409,273,782 with Prime Factorization

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

7 x 95 x 409 x 39 x 782 = 8294998530

Therefore, the lowest common multiple of 665,409,273,782 is 8294998530.

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 409 x 273 x 782 = 58064989710

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

409 : 1, 409

273 : 1, 3, 7, 13, 21, 39, 91, 273

782 : 1, 2, 17, 23, 34, 46, 391, 782

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,409,273,782, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

409:409

273:3x 7x 13

782:2x 17x 23

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

7 = 7

Therefore, the value for common factors is 7.

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 = 58064989710/(1x7)

LCM = 58064989710/7

LCM = 8294998530

Thus, we can understand that the LCM of 665,409,273,782 is 8294998530.
