Given numbers are 690,539,780,558

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

The LCM of 690,539,780,558 is 899278380.

Find LCM of 690,539,780,558 with Prime Factorization

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

2 x 3 x 5 x 23 x 539 x 26 x 93 = 899278380

Therefore, the lowest common multiple of 690,539,780,558 is 899278380.

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.

690 x 539 x 780 x 558 = 161870108400

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

539 : 1, 7, 11, 49, 77, 539

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,539,780,558, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

539:7x 7x 11

780:2x 2x 3x 5x 13

558:2x 3x 3x 31

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

2x 2x 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 161870108400/(1x180)

LCM = 161870108400/180

LCM = 899278380

Thus, we can understand that the LCM of 690,539,780,558 is 899278380.
