Given numbers are 620,780,260,562

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

The LCM of 620,780,260,562 is 6794580.

Find LCM of 620,780,260,562 with Prime Factorization

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

2 x 2 x 5 x 13 x 31 x 3 x 1 x 281 = 6794580

Therefore, the lowest common multiple of 620,780,260,562 is 6794580.

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 780 x 260 x 562 = 70663632000

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

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

562 : 1, 2, 281, 562

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,780,260,562, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

780:2x 2x 3x 5x 13

260:2x 2x 5x 13

562:2x 281

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 2x 5x 5x 13 = 5200

Therefore, the value for common factors is 5200.

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 = 70663632000/(2x5200)

LCM = 70663632000/10400

LCM = 6794580

Thus, we can understand that the LCM of 620,780,260,562 is 6794580.
