Given numbers are 620,104,136,772

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

The LCM of 620,104,136,772 is 52889720.

Find LCM of 620,104,136,772 with Prime Factorization

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

2 x 2 x 2 x 155 x 13 x 17 x 193 = 52889720

Therefore, the lowest common multiple of 620,104,136,772 is 52889720.

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 104 x 136 x 772 = 6769884160

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

104 : 1, 2, 4, 8, 13, 26, 52, 104

136 : 1, 2, 4, 8, 17, 34, 68, 136

772 : 1, 2, 4, 193, 386, 772

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,104,136,772, is 4.

Now, the common factors can be found like this.

620:2x 2x 5x 31

104:2x 2x 2x 13

136:2x 2x 2x 17

772:2x 2x 193

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 2 = 32

Therefore, the value for common factors is 32.

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 = 6769884160/(4x32)

LCM = 6769884160/128

LCM = 52889720

Thus, we can understand that the LCM of 620,104,136,772 is 52889720.
