The LCM of 531,988,679,399,490 is 12467784420.

Find LCM of 531,988,679,399,490 with Prime Factorization


2 531, 988, 679, 399, 490
3 531, 494, 679, 399, 245
7 177, 494, 679, 133, 245
19 177, 494, 97, 19, 35
177, 26, 97, 1, 35

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

2 x 3 x 7 x 19 x 177 x 26 x 97 x 1 x 35 = 12467784420

Therefore, the lowest common multiple of 531,988,679,399,490 is 12467784420.

LCM Formula to Find Lowest Common Multiple of 531,988,679,399,490

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.

531 x 988 x 679 x 399 x 490 = 69645043770120

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.

531 : 1, 3, 9, 59, 177, 531

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

679 : 1, 7, 97, 679

399 : 1, 3, 7, 19, 21, 57, 133, 399

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,988,679,399,490, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

988:2x 2x 13x 19

679:7x 97

399:3x 7x 19

490:2x 5x 7x 7

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 7x 19 = 5586

Therefore, the value for common factors is 5586.

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 = 69645043770120/(1x5586)

LCM = 69645043770120/5586

LCM = 12467784420

Thus, we can understand that the LCM of 531,988,679,399,490 is 12467784420.
