Given numbers are 620,440,506,770

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

The LCM of 620,440,506,770 is 2196040.

Find LCM of 620,440,506,770 with Prime Factorization

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

2 x 2 x 5 x 11 x 31 x 2 x 23 x 7 = 2196040

Therefore, the lowest common multiple of 620,440,506,770 is 2196040.

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 440 x 506 x 770 = 106288336000

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

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

506 : 1, 2, 11, 22, 23, 46, 253, 506

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,440,506,770, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

440:2x 2x 2x 5x 11

506:2x 11x 23

770:2x 5x 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.

2x 2x 2x 5x 5x 11x 11 = 24200

Therefore, the value for common factors is 24200.

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 = 106288336000/(2x24200)

LCM = 106288336000/48400

LCM = 2196040

Thus, we can understand that the LCM of 620,440,506,770 is 2196040.
