Find LCM of 644,987,759,530 with Prime Factorization


2 644, 987, 759, 530
3 322, 987, 759, 265
7 322, 329, 253, 265
23 46, 47, 253, 265
2, 47, 11, 265

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

2 x 3 x 7 x 23 x 2 x 47 x 11 x 265 = 264693660

Therefore, the lowest common multiple of 644,987,759,530 is 264693660.

LCM Formula to Find Lowest Common Multiple of 644,987,759,530

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.

644 x 987 x 759 x 530 = 255694075560

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

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

759 : 1, 3, 11, 23, 33, 69, 253, 759

530 : 1, 2, 5, 10, 53, 106, 265, 530

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,987,759,530, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

987:3x 7x 47

759:3x 11x 23

530:2x 5x 53

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 7x 23 = 966

Therefore, the value for common factors is 966.

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 = 255694075560/(1x966)

LCM = 255694075560/966

LCM = 264693660

Thus, we can understand that the LCM of 644,987,759,530 is 264693660.
