Given numbers are 221,343,122,168,862

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

The LCM of 221,343,122,168,862 is 47830480152.

Find LCM of 221,343,122,168,862 with Prime Factorization

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

2 x 7 x 221 x 49 x 61 x 12 x 431 = 47830480152

Therefore, the lowest common multiple of 221,343,122,168,862 is 47830480152.

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 343 x 122 x 168 x 862 = 1339253444256

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

343 : 1, 7, 49, 343

122 : 1, 2, 61, 122

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

862 : 1, 2, 431, 862

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,343,122,168,862, is 1.

Now, the common factors can be found like this.

221:13x 17

343:7x 7x 7

122:2x 61

168:2x 2x 2x 3x 7

862:2x 431

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 1339253444256/(1x28)

LCM = 1339253444256/28

LCM = 47830480152

Thus, we can understand that the LCM of 221,343,122,168,862 is 47830480152.
