Calculate the LCM of 686,680,327,997

Given numbers are 686,680,327,997

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

The LCM of 686,680,327,997 is 76040671560.

Find LCM of 686,680,327,997 with Prime Factorization


2 686, 680, 327, 997
343, 340, 327, 997

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

2 x 343 x 340 x 327 x 997 = 76040671560

Therefore, the lowest common multiple of 686,680,327,997 is 76040671560.

LCM Formula to Find Lowest Common Multiple of 686,680,327,997

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.

686 x 680 x 327 x 997 = 152081343120

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.

686 : 1, 2, 7, 14, 49, 98, 343, 686

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

327 : 1, 3, 109, 327

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,680,327,997, is 1.

Now, the common factors can be found like this.

686:2x 7x 7x 7

680:2x 2x 2x 5x 17

327:3x 109

997:997

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

2 = 2

Therefore, the value for common factors is 2.

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 = 152081343120/(1x2)

LCM = 152081343120/2

LCM = 76040671560

Thus, we can understand that the LCM of 686,680,327,997 is 76040671560.
