Given numbers are 620,556,711,436

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

The LCM of 620,556,711,436 is 6678863820.

Find LCM of 620,556,711,436 with Prime Factorization

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

2 x 2 x 155 x 139 x 711 x 109 = 6678863820

Therefore, the lowest common multiple of 620,556,711,436 is 6678863820.

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.

620 x 556 x 711 x 436 = 106861821120

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

556 : 1, 2, 4, 139, 278, 556

711 : 1, 3, 9, 79, 237, 711

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,556,711,436, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

556:2x 2x 139

711:3x 3x 79

436:2x 2x 109

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 106861821120/(1x16)

LCM = 106861821120/16

LCM = 6678863820

Thus, we can understand that the LCM of 620,556,711,436 is 6678863820.
