Calculate the LCM of 520,685,534,690

Given numbers are 520,685,534,690

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

The LCM of 520,685,534,690 is 437484840.

Find LCM of 520,685,534,690 with Prime Factorization


2 520, 685, 534, 690
3 260, 685, 267, 345
5 260, 685, 89, 115
52, 137, 89, 23

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

2 x 3 x 5 x 52 x 137 x 89 x 23 = 437484840

Therefore, the lowest common multiple of 520,685,534,690 is 437484840.

LCM Formula to Find Lowest Common Multiple of 520,685,534,690

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 685 x 534 x 690 = 131245452000

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

685 : 1, 5, 137, 685

534 : 1, 2, 3, 6, 89, 178, 267, 534

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,685,534,690, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

685:5x 137

534:2x 3x 89

690:2x 3x 5x 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 5 = 300

Therefore, the value for common factors is 300.

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 = 131245452000/(1x300)

LCM = 131245452000/300

LCM = 437484840

Thus, we can understand that the LCM of 520,685,534,690 is 437484840.
