Calculate the LCM of 400,525,749

Given numbers are 400,525,749

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

The LCM of 400,525,749 is 898800.

Find LCM of 400,525,749 with Prime Factorization


5 400, 525, 749
5 80, 105, 749
7 16, 21, 749
16, 3, 107

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

5 x 5 x 7 x 16 x 3 x 107 = 898800

Therefore, the lowest common multiple of 400,525,749 is 898800.

LCM Formula to Find Lowest Common Multiple of 400,525,749

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.

400 x 525 x 749 = 157290000

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,525,749, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

525:3x 5x 5x 7

749:7x 107

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

5x 5x 7 = 175

Therefore, the value for common factors is 175.

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 = 157290000/(1x175)

LCM = 157290000/175

LCM = 898800

Thus, we can understand that the LCM of 400,525,749 is 898800.
