Calculate the LCM of 676,988,421,418

Given numbers are 676,988,421,418

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

The LCM of 676,988,421,418 is 59480564.

Find LCM of 676,988,421,418 with Prime Factorization


2 676, 988, 421, 418
2 338, 494, 421, 209
13 169, 247, 421, 209
19 13, 19, 421, 209
13, 1, 421, 11

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

2 x 2 x 13 x 19 x 13 x 1 x 421 x 11 = 59480564

Therefore, the lowest common multiple of 676,988,421,418 is 59480564.

LCM Formula to Find Lowest Common Multiple of 676,988,421,418

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.

676 x 988 x 421 x 418 = 117533594464

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.

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

421 : 1, 421

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,988,421,418, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

988:2x 2x 13x 19

421:421

418:2x 11x 19

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 2x 13x 19 = 1976

Therefore, the value for common factors is 1976.

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 = 117533594464/(1x1976)

LCM = 117533594464/1976

LCM = 59480564

Thus, we can understand that the LCM of 676,988,421,418 is 59480564.
