Calculate the LCM of 649,675,445,520

Given numbers are 649,675,445,520

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

The LCM of 649,675,445,520 is 4054822200.

Find LCM of 649,675,445,520 with Prime Factorization


5 649, 675, 445, 520
649, 135, 89, 104

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

5 x 649 x 135 x 89 x 104 = 4054822200

Therefore, the lowest common multiple of 649,675,445,520 is 4054822200.

LCM Formula to Find Lowest Common Multiple of 649,675,445,520

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.

649 x 675 x 445 x 520 = 101370555000

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.

649 : 1, 11, 59, 649

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

445 : 1, 5, 89, 445

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,675,445,520, is 1.

Now, the common factors can be found like this.

649:11x 59

675:3x 3x 3x 5x 5

445:5x 89

520:2x 2x 2x 5x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 101370555000/(1x25)

LCM = 101370555000/25

LCM = 4054822200

Thus, we can understand that the LCM of 649,675,445,520 is 4054822200.
