Calculate the LCM of 297,857,789,462,142

Given numbers are 297,857,789,462,142

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

The LCM of 297,857,789,462,142 is 66539480238.

Find LCM of 297,857,789,462,142 with Prime Factorization


2 297, 857, 789, 462, 142
3 297, 857, 789, 231, 71
11 99, 857, 263, 77, 71
9, 857, 263, 7, 71

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

2 x 3 x 11 x 9 x 857 x 263 x 7 x 71 = 66539480238

Therefore, the lowest common multiple of 297,857,789,462,142 is 66539480238.

LCM Formula to Find Lowest Common Multiple of 297,857,789,462,142

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.

297 x 857 x 789 x 462 x 142 = 13174817087124

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

857 : 1, 857

789 : 1, 3, 263, 789

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,857,789,462,142, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

857:857

789:3x 263

462:2x 3x 7x 11

142:2x 71

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

2x 3x 3x 11 = 198

Therefore, the value for common factors is 198.

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 = 13174817087124/(1x198)

LCM = 13174817087124/198

LCM = 66539480238

Thus, we can understand that the LCM of 297,857,789,462,142 is 66539480238.
