The LCM of 397,676,819,749 is 1809095652.

Find LCM of 397,676,819,749 with Prime Factorization


7 397, 676, 819, 749
13 397, 676, 117, 107
397, 52, 9, 107

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

7 x 13 x 397 x 52 x 9 x 107 = 1809095652

Therefore, the lowest common multiple of 397,676,819,749 is 1809095652.

LCM Formula to Find Lowest Common Multiple of 397,676,819,749

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.

397 x 676 x 819 x 749 = 164627704332

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.

397 : 1, 397

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

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,676,819,749, is 1.

Now, the common factors can be found like this.

397:397

676:2x 2x 13x 13

819:3x 3x 7x 13

749:7x 107

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

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 164627704332/(1x91)

LCM = 164627704332/91

LCM = 1809095652

Thus, we can understand that the LCM of 397,676,819,749 is 1809095652.
