Find LCM of 385,207,782,681,818 with Prime Factorization


2 385, 207, 782, 681, 818
3 385, 207, 391, 681, 409
23 385, 69, 391, 227, 409
385, 3, 17, 227, 409

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

2 x 3 x 23 x 385 x 3 x 17 x 227 x 409 = 251570178090

Therefore, the lowest common multiple of 385,207,782,681,818 is 251570178090.

LCM Formula to Find Lowest Common Multiple of 385,207,782,681,818

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.

385 x 207 x 782 x 681 x 818 = 34716684576420

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

207 : 1, 3, 9, 23, 69, 207

782 : 1, 2, 17, 23, 34, 46, 391, 782

681 : 1, 3, 227, 681

818 : 1, 2, 409, 818

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,207,782,681,818, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

207:3x 3x 23

782:2x 17x 23

681:3x 227

818:2x 409

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

2x 3x 23 = 138

Therefore, the value for common factors is 138.

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 = 34716684576420/(1x138)

LCM = 34716684576420/138

LCM = 251570178090

Thus, we can understand that the LCM of 385,207,782,681,818 is 251570178090.
