Calculate the LCM of 522,786,420,959

Given numbers are 522,786,420,959

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

The LCM of 522,786,420,959 is 655783380.

Find LCM of 522,786,420,959 with Prime Factorization


2 522, 786, 420, 959
3 261, 393, 210, 959
7 87, 131, 70, 959
87, 131, 10, 137

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

2 x 3 x 7 x 87 x 131 x 10 x 137 = 655783380

Therefore, the lowest common multiple of 522,786,420,959 is 655783380.

LCM Formula to Find Lowest Common Multiple of 522,786,420,959

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.

522 x 786 x 420 x 959 = 165257411760

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.

522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522

786 : 1, 2, 3, 6, 131, 262, 393, 786

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

959 : 1, 7, 137, 959

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 522,786,420,959, is 1.

Now, the common factors can be found like this.

522:2x 3x 3x 29

786:2x 3x 131

420:2x 2x 3x 5x 7

959:7x 137

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 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 165257411760/(1x252)

LCM = 165257411760/252

LCM = 655783380

Thus, we can understand that the LCM of 522,786,420,959 is 655783380.
