Find LCM of 322,156,732,648,221 with Prime Factorization


2 322, 156, 732, 648, 221
2 161, 78, 366, 324, 221
3 161, 39, 183, 162, 221
13 161, 13, 61, 54, 221
161, 1, 61, 54, 17

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

2 x 2 x 3 x 13 x 161 x 1 x 61 x 54 x 17 = 1406445768

Therefore, the lowest common multiple of 322,156,732,648,221 is 1406445768.

LCM Formula to Find Lowest Common Multiple of 322,156,732,648,221

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.

322 x 156 x 732 x 648 x 221 = 5265732955392

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,156,732,648,221, is 1.

Now, the common factors can be found like this.

322:2x 7x 23

156:2x 2x 3x 13

732:2x 2x 3x 61

648:2x 2x 2x 3x 3x 3x 3

221:13x 17

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 2x 2x 3x 3x 13 = 3744

Therefore, the value for common factors is 3744.

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 = 5265732955392/(1x3744)

LCM = 5265732955392/3744

LCM = 1406445768

Thus, we can understand that the LCM of 322,156,732,648,221 is 1406445768.
