The LCM of 345,782,221,814 is 62063430.

Find LCM of 345,782,221,814 with Prime Factorization


2 345, 782, 221, 814
17 345, 391, 221, 407
23 345, 23, 13, 407
15, 1, 13, 407

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

2 x 17 x 23 x 15 x 1 x 13 x 407 = 62063430

Therefore, the lowest common multiple of 345,782,221,814 is 62063430.

LCM Formula to Find Lowest Common Multiple of 345,782,221,814

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.

345 x 782 x 221 x 814 = 48533602260

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.

345 : 1, 3, 5, 15, 23, 69, 115, 345

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

221 : 1, 13, 17, 221

814 : 1, 2, 11, 22, 37, 74, 407, 814

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,782,221,814, is 1.

Now, the common factors can be found like this.

345:3x 5x 23

782:2x 17x 23

221:13x 17

814:2x 11x 37

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

2x 17x 23 = 782

Therefore, the value for common factors is 782.

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 = 48533602260/(1x782)

LCM = 48533602260/782

LCM = 62063430

Thus, we can understand that the LCM of 345,782,221,814 is 62063430.
