Calculate the LCM of 961,900,984,639

Given numbers are 961,900,984,639

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

The LCM of 961,900,984,639 is 5035447800.

Find LCM of 961,900,984,639 with Prime Factorization


2 961, 900, 984, 639
2 961, 450, 492, 639
3 961, 225, 246, 639
3 961, 75, 82, 213
961, 25, 82, 71

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

2 x 2 x 3 x 3 x 961 x 25 x 82 x 71 = 5035447800

Therefore, the lowest common multiple of 961,900,984,639 is 5035447800.

LCM Formula to Find Lowest Common Multiple of 961,900,984,639

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.

961 x 900 x 984 x 639 = 543828362400

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.

961 : 1, 31, 961

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

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,900,984,639, is 1.

Now, the common factors can be found like this.

961:31x 31

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

984:2x 2x 2x 3x 41

639:3x 3x 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 3x 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 543828362400/(1x108)

LCM = 543828362400/108

LCM = 5035447800

Thus, we can understand that the LCM of 961,900,984,639 is 5035447800.
