Given numbers are 221,694,290,625

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

The LCM of 221,694,290,625 is 2779903750.

Find LCM of 221,694,290,625 with Prime Factorization

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

2 x 5 x 221 x 347 x 29 x 125 = 2779903750

Therefore, the lowest common multiple of 221,694,290,625 is 2779903750.

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.

221 x 694 x 290 x 625 = 27799037500

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.

221 : 1, 13, 17, 221

694 : 1, 2, 347, 694

290 : 1, 2, 5, 10, 29, 58, 145, 290

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 221,694,290,625, is 1.

Now, the common factors can be found like this.

221:13x 17

694:2x 347

290:2x 5x 29

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 5 = 10

Therefore, the value for common factors is 10.

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 = 27799037500/(1x10)

LCM = 27799037500/10

LCM = 2779903750

Thus, we can understand that the LCM of 221,694,290,625 is 2779903750.
