Given numbers are 743,817,817,693

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

The LCM of 743,817,817,693 is 420672483.

Find LCM of 743,817,817,693 with Prime Factorization

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

19 x 43 x 743 x 1 x 1 x 693 = 420672483

Therefore, the lowest common multiple of 743,817,817,693 is 420672483.

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.

743 x 817 x 817 x 693 = 343689418611

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.

743 : 1, 743

817 : 1, 19, 43, 817

817 : 1, 19, 43, 817

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,817,817,693, is 1.

Now, the common factors can be found like this.

743:743

817:19x 43

817:19x 43

693:3x 3x 7x 11

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

19x 43 = 817

Therefore, the value for common factors is 817.

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 = 343689418611/(1x817)

LCM = 343689418611/817

LCM = 420672483

Thus, we can understand that the LCM of 743,817,817,693 is 420672483.
