Calculate the LCM of 304,420,947,796

Given numbers are 304,420,947,796

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

The LCM of 304,420,947,796 is 6015419760.

Find LCM of 304,420,947,796 with Prime Factorization


2 304, 420, 947, 796
2 152, 210, 947, 398
76, 105, 947, 199

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

2 x 2 x 76 x 105 x 947 x 199 = 6015419760

Therefore, the lowest common multiple of 304,420,947,796 is 6015419760.

LCM Formula to Find Lowest Common Multiple of 304,420,947,796

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.

304 x 420 x 947 x 796 = 96246716160

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.

304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304

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

947 : 1, 947

796 : 1, 2, 4, 199, 398, 796

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 304,420,947,796, is 1.

Now, the common factors can be found like this.

304:2x 2x 2x 2x 19

420:2x 2x 3x 5x 7

947:947

796:2x 2x 199

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 2 = 16

Therefore, the value for common factors is 16.

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 = 96246716160/(1x16)

LCM = 96246716160/16

LCM = 6015419760

Thus, we can understand that the LCM of 304,420,947,796 is 6015419760.
