Calculate the LCM of 403,802,438

Given numbers are 403,802,438

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

The LCM of 403,802,438 is 70782114.

Find LCM of 403,802,438 with Prime Factorization


2 403, 802, 438
403, 401, 219

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

2 x 403 x 401 x 219 = 70782114

Therefore, the lowest common multiple of 403,802,438 is 70782114.

LCM Formula to Find Lowest Common Multiple of 403,802,438

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.

403 x 802 x 438 = 141564228

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.

403 : 1, 13, 31, 403

802 : 1, 2, 401, 802

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,802,438, is 1.

Now, the common factors can be found like this.

403:13x 31

802:2x 401

438:2x 3x 73

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 = 141564228/(1x2)

LCM = 141564228/2

LCM = 70782114

Thus, we can understand that the LCM of 403,802,438 is 70782114.
