Calculate the LCM of 520,424,694,990

Given numbers are 520,424,694,990

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

The LCM of 520,424,694,990 is 946768680.

Find LCM of 520,424,694,990 with Prime Factorization


2 520, 424, 694, 990
2 260, 212, 347, 495
2 130, 106, 347, 495
5 65, 53, 347, 495
13, 53, 347, 99

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

2 x 2 x 2 x 5 x 13 x 53 x 347 x 99 = 946768680

Therefore, the lowest common multiple of 520,424,694,990 is 946768680.

LCM Formula to Find Lowest Common Multiple of 520,424,694,990

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.

520 x 424 x 694 x 990 = 151482988800

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

424 : 1, 2, 4, 8, 53, 106, 212, 424

694 : 1, 2, 347, 694

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,424,694,990, is 2.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

424:2x 2x 2x 53

694:2x 347

990:2x 3x 3x 5x 11

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 2x 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 151482988800/(2x80)

LCM = 151482988800/160

LCM = 946768680

Thus, we can understand that the LCM of 520,424,694,990 is 946768680.
