Calculate the LCM of 556,552,418,142

Given numbers are 556,552,418,142

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

The LCM of 556,552,418,142 is 1138566792.

Find LCM of 556,552,418,142 with Prime Factorization


2 556, 552, 418, 142
2 278, 276, 209, 71
139, 138, 209, 71

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

2 x 2 x 139 x 138 x 209 x 71 = 1138566792

Therefore, the lowest common multiple of 556,552,418,142 is 1138566792.

LCM Formula to Find Lowest Common Multiple of 556,552,418,142

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.

556 x 552 x 418 x 142 = 18217068672

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.

556 : 1, 2, 4, 139, 278, 556

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

418 : 1, 2, 11, 19, 22, 38, 209, 418

142 : 1, 2, 71, 142

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,552,418,142, is 2.

Now, the common factors can be found like this.

556:2x 2x 139

552:2x 2x 2x 3x 23

418:2x 11x 19

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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 18217068672/(2x8)

LCM = 18217068672/16

LCM = 1138566792

Thus, we can understand that the LCM of 556,552,418,142 is 1138566792.
