Given numbers are 402,342,572,122,121

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

The LCM of 402,342,572,122,121 is 4397334084.

Find LCM of 402,342,572,122,121 with Prime Factorization

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

2 x 3 x 11 x 67 x 57 x 26 x 61 x 11 = 4397334084

Therefore, the lowest common multiple of 402,342,572,122,121 is 4397334084.

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.

402 x 342 x 572 x 122 x 121 = 1160896198176

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

122 : 1, 2, 61, 122

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,342,572,122,121, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

342:2x 3x 3x 19

572:2x 2x 11x 13

122:2x 61

121:11x 11

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 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 1160896198176/(1x264)

LCM = 1160896198176/264

LCM = 4397334084

Thus, we can understand that the LCM of 402,342,572,122,121 is 4397334084.
