The LCM of 676,649,991,966 is 209996558772.

Find LCM of 676,649,991,966 with Prime Factorization


2 676, 649, 991, 966
338, 649, 991, 483

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

2 x 338 x 649 x 991 x 483 = 209996558772

Therefore, the lowest common multiple of 676,649,991,966 is 209996558772.

LCM Formula to Find Lowest Common Multiple of 676,649,991,966

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 649 x 991 x 966 = 419993117544

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

649 : 1, 11, 59, 649

991 : 1, 991

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,649,991,966, is 1.

Now, the common factors can be found like this.

676:2x 2x 13x 13

649:11x 59

991:991

966:2x 3x 7x 23

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 = 419993117544/(1x2)

LCM = 419993117544/2

LCM = 209996558772

Thus, we can understand that the LCM of 676,649,991,966 is 209996558772.
