Calculate the LCM of 930,869,630,644

Given numbers are 930,869,630,644

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

The LCM of 930,869,630,644 is 780692220.

Find LCM of 930,869,630,644 with Prime Factorization


2 930, 869, 630, 644
3 465, 869, 315, 322
5 155, 869, 105, 322
7 31, 869, 21, 322
31, 869, 3, 46

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

2 x 3 x 5 x 7 x 31 x 869 x 3 x 46 = 780692220

Therefore, the lowest common multiple of 930,869,630,644 is 780692220.

LCM Formula to Find Lowest Common Multiple of 930,869,630,644

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.

930 x 869 x 630 x 644 = 327890732400

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.

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

869 : 1, 11, 79, 869

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 930,869,630,644, is 1.

Now, the common factors can be found like this.

930:2x 3x 5x 31

869:11x 79

630:2x 3x 3x 5x 7

644:2x 2x 7x 23

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 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 327890732400/(1x420)

LCM = 327890732400/420

LCM = 780692220

Thus, we can understand that the LCM of 930,869,630,644 is 780692220.
