Given numbers are 155,170,416,625

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

The LCM of 155,170,416,625 is 137020000.

Find LCM of 155,170,416,625 with Prime Factorization

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

2 x 5 x 31 x 17 x 208 x 125 = 137020000

Therefore, the lowest common multiple of 155,170,416,625 is 137020000.

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.

155 x 170 x 416 x 625 = 6851000000

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.

155 : 1, 5, 31, 155

170 : 1, 2, 5, 10, 17, 34, 85, 170

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,170,416,625, is 1.

Now, the common factors can be found like this.

155:5x 31

170:2x 5x 17

416:2x 2x 2x 2x 2x 13

625:5x 5x 5x 5

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 6851000000/(1x50)

LCM = 6851000000/50

LCM = 137020000

Thus, we can understand that the LCM of 155,170,416,625 is 137020000.
