The LCM of 210,255,221,743 is 34482630.

Find LCM of 210,255,221,743 with Prime Factorization


3 210, 255, 221, 743
5 70, 85, 221, 743
17 14, 17, 221, 743
14, 1, 13, 743

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

3 x 5 x 17 x 14 x 1 x 13 x 743 = 34482630

Therefore, the lowest common multiple of 210,255,221,743 is 34482630.

LCM Formula to Find Lowest Common Multiple of 210,255,221,743

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.

210 x 255 x 221 x 743 = 8793070650

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

255 : 1, 3, 5, 15, 17, 51, 85, 255

221 : 1, 13, 17, 221

743 : 1, 743

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,255,221,743, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

255:3x 5x 17

221:13x 17

743:743

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

3x 5x 17 = 255

Therefore, the value for common factors is 255.

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 = 8793070650/(1x255)

LCM = 8793070650/255

LCM = 34482630

Thus, we can understand that the LCM of 210,255,221,743 is 34482630.
