Calculate the LCM of 451,987,738,650

Given numbers are 451,987,738,650

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

The LCM of 451,987,738,650 is 868017150.

Find LCM of 451,987,738,650 with Prime Factorization


2 451, 987, 738, 650
3 451, 987, 369, 325
41 451, 329, 123, 325
11, 329, 3, 325

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

2 x 3 x 41 x 11 x 329 x 3 x 325 = 868017150

Therefore, the lowest common multiple of 451,987,738,650 is 868017150.

LCM Formula to Find Lowest Common Multiple of 451,987,738,650

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.

451 x 987 x 738 x 650 = 213532218900

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.

451 : 1, 11, 41, 451

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

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,987,738,650, is 1.

Now, the common factors can be found like this.

451:11x 41

987:3x 7x 47

738:2x 3x 3x 41

650:2x 5x 5x 13

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 41 = 246

Therefore, the value for common factors is 246.

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 = 213532218900/(1x246)

LCM = 213532218900/246

LCM = 868017150

Thus, we can understand that the LCM of 451,987,738,650 is 868017150.
