Find LCM of 828,782,508,669 with Prime Factorization


2 828, 782, 508, 669
2 414, 391, 254, 669
3 207, 391, 127, 669
23 69, 391, 127, 223
3, 17, 127, 223

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

2 x 2 x 3 x 23 x 3 x 17 x 127 x 223 = 398646396

Therefore, the lowest common multiple of 828,782,508,669 is 398646396.

LCM Formula to Find Lowest Common Multiple of 828,782,508,669

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.

828 x 782 x 508 x 669 = 220052810592

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.

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

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

508 : 1, 2, 4, 127, 254, 508

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,782,508,669, is 1.

Now, the common factors can be found like this.

828:2x 2x 3x 3x 23

782:2x 17x 23

508:2x 2x 127

669:3x 223

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 3x 23 = 552

Therefore, the value for common factors is 552.

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 = 220052810592/(1x552)

LCM = 220052810592/552

LCM = 398646396

Thus, we can understand that the LCM of 828,782,508,669 is 398646396.
