Calculate the LCM of 703,642,442

Given numbers are 703,642,442

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

The LCM of 703,642,442 is 99743046.

Find LCM of 703,642,442 with Prime Factorization


2 703, 642, 442
703, 321, 221

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

2 x 703 x 321 x 221 = 99743046

Therefore, the lowest common multiple of 703,642,442 is 99743046.

LCM Formula to Find Lowest Common Multiple of 703,642,442

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.

703 x 642 x 442 = 199486092

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.

703 : 1, 19, 37, 703

642 : 1, 2, 3, 6, 107, 214, 321, 642

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 703,642,442, is 1.

Now, the common factors can be found like this.

703:19x 37

642:2x 3x 107

442:2x 13x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 199486092/(1x2)

LCM = 199486092/2

LCM = 99743046

Thus, we can understand that the LCM of 703,642,442 is 99743046.
