Given numbers are 553,669,621,743

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

The LCM of 553,669,621,743 is 56899756557.

Find LCM of 553,669,621,743 with Prime Factorization

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

3 x 553 x 223 x 207 x 743 = 56899756557

Therefore, the lowest common multiple of 553,669,621,743 is 56899756557.

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.

553 x 669 x 621 x 743 = 170699269671

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.

553 : 1, 7, 79, 553

669 : 1, 3, 223, 669

621 : 1, 3, 9, 23, 27, 69, 207, 621

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,669,621,743, is 1.

Now, the common factors can be found like this.

553:7x 79

669:3x 223

621:3x 3x 3x 23

743:743

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

3 = 3

Therefore, the value for common factors is 3.

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 = 170699269671/(1x3)

LCM = 170699269671/3

LCM = 56899756557

Thus, we can understand that the LCM of 553,669,621,743 is 56899756557.
