Given numbers are 620,291,175,855,136

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

The LCM of 620,291,175,855,136 is 12237888600.

Find LCM of 620,291,175,855,136 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 97 x 35 x 57 x 34 = 12237888600

Therefore, the lowest common multiple of 620,291,175,855,136 is 12237888600.

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 291 x 175 x 855 x 136 = 3671366580000

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

291 : 1, 3, 97, 291

175 : 1, 5, 7, 25, 35, 175

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,291,175,855,136, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

291:3x 97

175:5x 5x 7

855:3x 3x 5x 19

136:2x 2x 2x 17

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 5x 5 = 300

Therefore, the value for common factors is 300.

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 = 3671366580000/(1x300)

LCM = 3671366580000/300

LCM = 12237888600

Thus, we can understand that the LCM of 620,291,175,855,136 is 12237888600.
