Calculate the LCM of 777,998,222,987

Given numbers are 777,998,222,987

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

The LCM of 777,998,222,987 is 36445962.

Find LCM of 777,998,222,987 with Prime Factorization


2 777, 998, 222, 987
3 777, 499, 111, 987
7 259, 499, 37, 329
37 37, 499, 37, 47
1, 499, 1, 47

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

2 x 3 x 7 x 37 x 1 x 499 x 1 x 47 = 36445962

Therefore, the lowest common multiple of 777,998,222,987 is 36445962.

LCM Formula to Find Lowest Common Multiple of 777,998,222,987

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.

777 x 998 x 222 x 987 = 169911074844

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

998 : 1, 2, 499, 998

222 : 1, 2, 3, 6, 37, 74, 111, 222

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,998,222,987, is 1.

Now, the common factors can be found like this.

777:3x 7x 37

998:2x 499

222:2x 3x 37

987:3x 7x 47

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

2x 3x 3x 7x 37 = 4662

Therefore, the value for common factors is 4662.

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 = 169911074844/(1x4662)

LCM = 169911074844/4662

LCM = 36445962

Thus, we can understand that the LCM of 777,998,222,987 is 36445962.
