Given numbers are 772,193,161,221

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

The LCM of 772,193,161,221 is 27468532.

Find LCM of 772,193,161,221 with Prime Factorization

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

193 x 4 x 1 x 161 x 221 = 27468532

Therefore, the lowest common multiple of 772,193,161,221 is 27468532.

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.

772 x 193 x 161 x 221 = 5301426676

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.

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

193 : 1, 193

161 : 1, 7, 23, 161

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,193,161,221, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

193:193

161:7x 23

221:13x 17

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

193 = 193

Therefore, the value for common factors is 193.

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 = 5301426676/(1x193)

LCM = 5301426676/193

LCM = 27468532

Thus, we can understand that the LCM of 772,193,161,221 is 27468532.
