Calculate the LCM of 397,961,166,900

Given numbers are 397,961,166,900

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

The LCM of 397,961,166,900 is 28499319900.

Find LCM of 397,961,166,900 with Prime Factorization


2 397, 961, 166, 900
397, 961, 83, 450

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

2 x 397 x 961 x 83 x 450 = 28499319900

Therefore, the lowest common multiple of 397,961,166,900 is 28499319900.

LCM Formula to Find Lowest Common Multiple of 397,961,166,900

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.

397 x 961 x 166 x 900 = 56998639800

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.

397 : 1, 397

961 : 1, 31, 961

166 : 1, 2, 83, 166

900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,961,166,900, is 1.

Now, the common factors can be found like this.

397:397

961:31x 31

166:2x 83

900:2x 2x 3x 3x 5x 5

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 = 56998639800/(1x2)

LCM = 56998639800/2

LCM = 28499319900

Thus, we can understand that the LCM of 397,961,166,900 is 28499319900.
