Calculate the LCM of 169,456,728

Given numbers are 169,456,728

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

The LCM of 169,456,728 is 539448.

Find LCM of 169,456,728 with Prime Factorization


2 169, 456, 728
2 169, 228, 364
2 169, 114, 182
13 169, 57, 91
13, 57, 7

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

2 x 2 x 2 x 13 x 13 x 57 x 7 = 539448

Therefore, the lowest common multiple of 169,456,728 is 539448.

LCM Formula to Find Lowest Common Multiple of 169,456,728

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.

169 x 456 x 728 = 56102592

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.

169 : 1, 13, 169

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,456,728, is 1.

Now, the common factors can be found like this.

169:13x 13

456:2x 2x 2x 3x 19

728:2x 2x 2x 7x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 56102592/(1x104)

LCM = 56102592/104

LCM = 539448

Thus, we can understand that the LCM of 169,456,728 is 539448.
