Calculate the LCM of 509,962,507,642

Given numbers are 509,962,507,642

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

The LCM of 509,962,507,642 is 2043342834.

Find LCM of 509,962,507,642 with Prime Factorization


2 509, 962, 507, 642
3 509, 481, 507, 321
13 509, 481, 169, 107
509, 37, 13, 107

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

2 x 3 x 13 x 509 x 37 x 13 x 107 = 2043342834

Therefore, the lowest common multiple of 509,962,507,642 is 2043342834.

LCM Formula to Find Lowest Common Multiple of 509,962,507,642

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.

509 x 962 x 507 x 642 = 159380741052

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.

509 : 1, 509

962 : 1, 2, 13, 26, 37, 74, 481, 962

507 : 1, 3, 13, 39, 169, 507

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,962,507,642, is 1.

Now, the common factors can be found like this.

509:509

962:2x 13x 37

507:3x 13x 13

642:2x 3x 107

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 13 = 78

Therefore, the value for common factors is 78.

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 = 159380741052/(1x78)

LCM = 159380741052/78

LCM = 2043342834

Thus, we can understand that the LCM of 509,962,507,642 is 2043342834.
