Given numbers are 221,121,796,370

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

The LCM of 221,121,796,370 is 3937879660.

Find LCM of 221,121,796,370 with Prime Factorization

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

2 x 221 x 121 x 398 x 185 = 3937879660

Therefore, the lowest common multiple of 221,121,796,370 is 3937879660.

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 121 x 796 x 370 = 7875759320

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

121 : 1, 11, 121

796 : 1, 2, 4, 199, 398, 796

370 : 1, 2, 5, 10, 37, 74, 185, 370

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,121,796,370, is 1.

Now, the common factors can be found like this.

221:13x 17

121:11x 11

796:2x 2x 199

370:2x 5x 37

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

2 = 2

Therefore, the value for common factors is 2.

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 = 7875759320/(1x2)

LCM = 7875759320/2

LCM = 3937879660

Thus, we can understand that the LCM of 221,121,796,370 is 3937879660.
