Calculate the LCM of 308,771,661,386

Given numbers are 308,771,661,386

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

The LCM of 308,771,661,386 is 30294505164.

Find LCM of 308,771,661,386 with Prime Factorization


2 308, 771, 661, 386
154, 771, 661, 193

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

2 x 154 x 771 x 661 x 193 = 30294505164

Therefore, the lowest common multiple of 308,771,661,386 is 30294505164.

LCM Formula to Find Lowest Common Multiple of 308,771,661,386

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.

308 x 771 x 661 x 386 = 60589010328

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.

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

771 : 1, 3, 257, 771

661 : 1, 661

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,771,661,386, is 1.

Now, the common factors can be found like this.

308:2x 2x 7x 11

771:3x 257

661:661

386:2x 193

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 = 60589010328/(1x2)

LCM = 60589010328/2

LCM = 30294505164

Thus, we can understand that the LCM of 308,771,661,386 is 30294505164.
